SAFETY

Product Safety and RF Exposure for Portable Two-Way Radios

THIS CHAPTER IS AN EXTRACT OF THE MULTI LINGUAL PORTABLE SAFETY
BOOKLET PUBLICATION No. 6864117B25. FOR THE LATEST SAFETY
INFORMATION REFER TO THE SEPARATE SAFETY BOOKLET DELIVERED WITH
YOUR RADIO.

BEFORE USING THIS RADIO, READ THIS BOOKLET WHICH CONTAINS IMPORTANT OPERATING
INSTRUCTIONS FOR SAFE USAGE AND RF ENERGY AWARENESS AND CONTROL INFORMATION AND
OPERATIONAL INSTRUCTIONS FOR COMPLIANCE WITH RF ENERGY EXPOSURE LIMITS IN
APPLICABLE NATIONAL AND INTERNATIONAL STANDARDS. ALSO READ THE OPERATIONAL
INSTRUCTIONS FOR SAFE USAGE. FOR RADIOS THAT HAVE BEEN APPROVED AS INTRINSICALLY
SAFE, READ THE INSTRUCTIONS AND INFORMATION ON INTRINSIC SAFETY ON PAGE VII

.

RF Energy Exposure Awareness and Control Information and Operational Instructions for Occupational Use

NOTICE: This radio is intended for use in occupational/controlled conditions where users

have full knowledge of their exposure and can exercise control over their exposure
to meet the occupational limits in FCC/ICNIRP and International standards. This
radio device is NOT authorized for general population consumer use.

This two-way radio uses electromagnetic energy in the radio frequency (RF) spectrum to provide
communications between two or more users over a distance. It uses radio frequency (RF) energy or
radio waves to send and receive calls. RF energy is one form of electromagnetic energy. Other
forms include, but are not limited to, sunlight and x-rays. RF energy, however, should not be
confused with these other forms of electromagnetic energy, which when used improperly, can cause
biological damage. Very high levels of x-rays, for example, can damage tissues and genetic
material.

Experts in science, engineering, medicine, health, and industry work with organizations to develop
standards for safe exposure to RF energy. These standards provide recommended levels of RF
exposure for both workers and the general public. These recommended RF exposure levels include
substantial margins of protection.

All Motorola two-way radios are designed, manufactured, and tested to ensure they meet
government-established RF exposure levels. In addition, manufacturers also recommend specific
operating instructions to users of two-way radios. These instructions are important because they
inform users about RF energy exposure and provide simple procedures on how to control it.

Please refer to the following websites for more information on what RF energy exposure is and how
to control your exposure to assure compliance with established RF exposure limits:

http://www.fcc.gov/oet/rfsafety/rf-faqs.html

http://www.osha.gov/SLTC/radiofrequencyradiation/index.html

vi MTH800 TETRA Handportable Terminal / Basic Service Manual SAFETY

Federal Communication Commission (FCC) Regulations (US markets only)

The FCC rules require manufacturers to comply with the FCC RF energy exposure limits for portable
two-way radios before they can be marketed in the U.S. When two-way radios are used as a
consequence of employment, the FCC requires users to be fully aware of and able to control their
exposure to meet occupational requirements. Exposure awareness can be facilitated by the use of a
product label directing users to specific user awareness information. Your Motorola two-way radio
has a RF Exposure Product Label. Do not remove this RF Exposure Label from the device. Also,
your Motorola user manual, or separate safety booklet includes information and operating
instructions required to control your RF exposure and to satisfy compliance requirements.

Compliance with RF Exposure Standards

Your Motorola two-way radio is designed and tested to comply with a number of national and
International standards and guidelines (listed below) for human exposure to radio frequency
electromagnetic energy. This radio complies with the IEEE (FCC) and ICNIRP exposure limits

for occupational/controlled RF exposure environments at operating duty factors of up to 50%
talk-50% listen and is authorized by the IEEE/ICNIRP for occupational use only.

In terms of measuring RF energy for compliance with these exposure guidelines, your radio
generates measurable RF energy only while it is transmitting (during talking), not when it is
receiving (listening) or in standby mode.

NOTE:The approved batteries, supplied with the portable radio, are rated for a 5-5-90 duty cycle

(5% talk–5% listen–90% standby), even though this radio complies with IEEE/ICNIRP
occupational exposure limits at usage factors of up to 50% talk.

Your Motorola two-way radio complies with the following RF energy exposure standards and
guidelines:

• United States Federal Communications Commission, Code of Federal Regulations; 47 CFR part
2 sub-part J

• American National Standards Institute (ANSI) / Institute of Electrical and Electronic Engineers
(IEEE) C95. 1-1992

• Institute of Electrical and Electronic Engineers (IEEE) C95.1-1999 Edition

• International Commission on Non-Ionizing Radiation Protection (ICNIRP) 1998

• Ministry of Health (Canada) Safety Code 6. Limits of Human Exposure to Radiofrequency
Electromagnetic Fields in the Frequency Range from 3 kHz to 300 GHz, 1999

• Australian Communications Authority Radiocommunications (Electromagnetic Radiation ­Human Exposure) Standard, 2003

• ANATEL ANNEX to Resolution No. 303 of July 2, 2002 "Regulation of limitation of exposure to
electrical, magnetic and electromagnetic fields in the radio frequency range between 9 KHz and
300 GHz" and "Attachment to resolution # 303 from July 2, 2002"

SAFETY MTH800 TETRA Handportable Terminal / Basic Service Manual vii

RF Exposure Compliance and Control Guidelines and Operating Instructions

To control your exposure and ensure compliance with the occupational/controlled environment
exposure limits, always adhere to the following procedures:

Guidelines:

• User awareness instructions should accompany device when transferred to other users.

• Do not use this device if the operational requirements described herein are not met.

Operating Instructions:

• Transmit no more than the rated duty factor of 50% of the time. To transmit (talk), push the Push­To-Talk (PTT) button. To receive calls, release the PTT button. Transmitting 50% of the time, or
less, is important because this radio generates measurable RF energy exposure only when
transmitting (in terms of measuring for standards compliance).

• When worn on the body, always place the radio in a Motorola-approved clip, holder, holster,
case, or body harness for this product. Using approved body-worn accessories is important
because the use of non-Motorola-approved accessories may result in exposure levels, which
exceed the IEEE/ICNIRP occupational/controlled environment RF exposure limits.

• If you are not using a body-worn accessory and are not using the radio in the intended use
position, along side the head in the phone mode (TETRA only), in front of the face in the hand
held mode, then ensure the antenna and the radio are kept 2.5 cm (one inch) from the body
when transmitting. Keeping the radio at a proper distance is important because RF exposures
decrease with increasing distance from the antenna.

Hand-held Mode - Operating Instructions:

• Hold the radio in a vertical position in front of the face with the microphone (and
other parts of the radio including the antenna) at least 2.5 cm (one inch) away from
the nose or lips. Antenna should be kept away from the eye. Keeping the radio at a
proper distance is important since RF exposures decrease with increasing distance
from the antenna.

Phone Mode (TETRA only) - Operating Instructions:

• When placing or receiving a phone call, hold your radio product as you would a wireless
telephone. Speak directly into the microphone.

Approved Accessories

• Use only Motorola-approved supplied or replacement antennas, batteries, and accessories. Use
of non–Motorola - approved antennas, batteries and accessories may exceed IEEE/ICNIRP RF
exposure guidelines. For a list of Motorola-approved antennas, batteries, and other accessories
please see your dealer or local Motorola contact. Your nearest dealer can be found at the
following web site:

Electromagnetic Interference/Compatibility

NOTE:Nearly every electronic device is susceptible to electromagnetic interference (EMI) if

inadequately shielded, designed, or otherwise configured for electromagnetic compatibility.

Facilities

To avoid electromagnetic interference and/or compatibility conflicts, turn off your radio in any facility
where posted notices instruct you to do so. Hospitals or health care facilities may be using
equipment that is sensitive to external RF energy.

Aircraft

When instructed to do so, turn off your radio when on board an aircraft. Any use of a radio must be
in accordance with applicable regulations per airline crew instructions.

Medical Devices

Pacemakers

The Advanced Medical Technology Association (AdvaMed) recommends that a minimum separation
of 15 centimeters (6 inches) be maintained between a handheld wireless radio and a pacemaker.
These recommendations are consistent with those of the U.S. Food and Drug Administration.
Persons with pacemakers should:

• ALWAYS keep the radio more than 15 centimeters from their pacemaker when the radio is turned
ON.

• Not carry the radio in the breast pocket.

• Use the ear opposite the pacemaker to minimize the potential for interference.

• Turn the radio OFF immediately if you have any reason to suspect that interference is taking
place.

Hearing Aids

Some digital wireless radios may interfere with some hearing aids. In the event of such interference,
you may want to consult your hearing aid manufacturer to discuss alternatives.

Other Medical Devices

If you use any other personal medical device, consult the manufacturer of your device to determine
if it is adequately shielded from RF energy. Your physician may be able to assist you in obtaining this
information.

SAFETY MTH800 TETRA Handportable Terminal / Basic Service Manual ix

Use of Communication Devices While Driving

Always check the laws and regulations on the use of radios in the area where you drive.

• Give full attention to driving and to the road.

• Use hands-free operation, if available.

• Pull off the road and park before making or answering a call if driving conditions or regulations so
require.

Operational Warnings

For Vehicles With An Air Bag
Refer to vehicle manufacturer's manual prior to installation of electronic equipment to avoid

interference with air bag wiring.

Do not place a portable radio in the area over an air bag or in the air bag deployment area. Air bags
inflate with great force. If a portable radio is placed in the air bag deployment area and the air bag
inflates, the radio may be propelled with great force and cause serious injury to occupants of the
vehicle.

Potentially Explosive Atmospheres
(Explosive atmospheres refers to hazard classified locations that may contain hazardous

gas, vapors, or dusts.)

Turn off your radio prior to entering any area with a potentially explosive atmosphere, unless it is a
radio type especially qualified for use in such areas as "Intrinsically Safe" (for example, Factory
Mutual, CSA, UL, CENELEC or ATEX Approved). Do not remove, install, or charge batteries in such
areas. Sparks in a potentially explosive atmosphere can cause an explosion or fire resulting in
bodily injury or even death.

The areas with potentially explosive atmospheres referred to above include fuelling areas such as
below decks on boats, fuel or chemical transfer or storage facilities, areas where the air contains
chemicals or particles, such as grain, dust or metal powders. Areas with potentially explosive
atmospheres are often but not always posted.

Blasting Caps And Blasting Areas

To avoid possible interference with blasting operations, turn off your radio when you are near
electrical blasting caps, in a blasting area, or in areas posted:

"Turn off two-way radio". Obey all signs and instructions.

Operational Cautions

Antennas

Do not use any portable radio that has a damaged antenna. If a damaged antenna comes into contact
with your skin, a minor burn can result.

Batteries

All batteries can cause property damage and/or bodily injury such as burns if a conductive material
such as jewelry, keys, or beaded chains touch exposed terminals. The conductive material may
complete an electrical circuit (short circuit) and become quite hot. Exercise care in handling any
charged battery, particularly when placing it inside a pocket, purse, or other container with metal
objects.

xMTH800 TETRA Handportable Terminal / Basic Service Manual SAFETY

Intrinsically Safe Radio Information

The Intrinsically safe approval unit refers to a product that has been approved as intrinsically safe by
an approval agency (for example FM Approvals, CSA, UL, CENELEC or ATEX) and certifies that a
particular product meets the Agency's applicable intrinsic safety standards for specific types of
hazardous classified locations. A portable radio that has been approved for intrinsic safety will have
Approval label attached to the radio to identify the unit as being Approved for specified hazardous
atmospheres. This label specifies the hazardous Class/Division/Group along with the part number of
the battery that must be used. The Intrinsically Safe Approval Label will be located on the portable
radio unit.

Operational Cautions for Intrinsic Safe Equipment

• Do not operate radio communications equipment in a hazardous atmosphere unless it is a type
especially qualified (for example, FM, UL, CSA, or CENELEC or ATEX approved). An explosion or
fire may result.

• Do not operate a radio unit that has been approved as intrinsically safe product in a hazardous
atmosphere if it has been physically damaged (for example, cracked housing). An explosion or fire
may result.

• Do not replace or charge batteries in a hazardous atmosphere. Contact sparking may occur while
installing or removing batteries and cause an explosion or fire.

Operational Cautions for Intrinsic Safe Equipment

Radios must ship from the Motorola manufacturing facility with the hazardous atmosphere capability
and the intrinsic safety approval labelling (FM, UL, CSA, CENELEC or ATEX). Radios will not be
upgraded to this capability and labeled once they have been shipped to the field.

A modification changes the unit’s hardware from its original design configuration. Modifications can
only be made by the original product manufacturer.

• Do not replace or change accessories in a hazardous atmosphere. Contact sparking may
occur while installing or removing accessories and cause an explosion or fire.

• Turn the radio off before removing or installing a battery or accessory.

• Do not disassemble an intrinsically safe product in any way that exposes the internal
circuits of the unit.

• Failure to use an intrinsically safe approved battery or Approved accessories specifically
approved for the radio unit may result in the dangerously unsafe condition of an
unapproved radio combination being used in a hazardous location.

• Unauthorized or incorrect modification of the intrinsically safe approved Product will
negate the approval rating of the product.

• Incorrect repair or relabeling of any intrinsically safe Agency-approved radio could
adversely affect the Approval rating of the unit.

• Use of a radio that is not intrinsically safe in a hazardous atmosphere could result in
serious injury or death.

SAFETY MTH800 TETRA Handportable Terminal / Basic Service Manual xi

Repair

REPAIRS FOR MOTOROLA PRODUCTS WITH INTRINSICALLY SAFE APPROVAL ARE THE
RESPONSIBILITY OF THE USER.

• Repairs to a Motorola FM approved radio product should only be done at a location that
has been FM audited under the FM 3605 repairs and service standard.

• Contact Motorola for assistance regarding repairs and service of Motorola intrinsically
safe equipment.

A repair constitutes something done internally to the unit that would bring it back to its original
condition.

Items not considered as repairs are those in which an action is performed on a unit which does not
require the outer casing of the unit to be opened in a manner which exposes the internal electrical
circuits of the unit.

Do Not Substitute Options or Accessories

The Motorola communications equipment certified as intrinsically safe by the approving agency,
(FM, UL, CSA, CENELEC or ATEX) is tested as a complete system which consists of the listed
agency Approved portable, Approved battery, and Approved accessories or options, or both. This
Approved portable and battery combination must be strictly observed. There must be no substitution
of items, even if the substitute has been previously Approved with a different Motorola
communications equipment unit. Approved configurations are listed by the Approving Agency (FM,
UL, CSA, CENELEC or ATEX).

The Intrinsically Safe Approval Label affixed to radio refers to the intrinsically safe classification of
that radio product, and the approved batteries that can be used with that system.

The manual PN referenced on the Intrinsically Safe Approval Label identifies the approved
Accessories and or options that can be used with that portable radio unit.

Using a non Motorola intrinsically safe battery and or accessory with the Motorola approved radio
unit will void the intrinsically safe approval of that radio unit.

Digital Modulation Technology MTH800 TETRA Handportable Terminal / Basic Service Manual 3 - 1

CHAPTER 3

OVERVIEW

To achieve a high spectrum efficiency, the MTH800 uses digital modulation
technology and sophisticated voice-compression algorithm. The voice of the
person speaking into the microphone is converted into a digital bit stream
consisting of zeros (0) and ones (1). This stream is then modulated into a radio­frequency (RF) signal, which is transmitted over the air to another terminal. The
process is called digital modulation.

Digital Modulation Technology

The MTH800 is a 380-430 or 440-470MHz TETRA Handportable Terminal that
can operate in dispatch and phone modes. The terminal can also operate in TMO
(Trunked Mode Operation) and DMO (Direct Mode Operation) modes. It uses two
digital technologies:

π/4 DQPSK and Time Division Multiple Access (TDMA).

π/4 DQPSK is a modulation technique that transmits information by altering the

phase of the radio frequency (RF) signal. Data is converted into complex
symbols, which alter the RF signal and transmit the information. When the signal
is received, the change in phase is converted back into symbols and then into the
original data.

The system can accommodate 4-voice channels in the standard 25 kHz channel
as used in the two-way terminal.

Time Division Multiple Access (TDMA) is used to allocate portions of the RF
signal by dividing time into four slots, one for each unit.

Time allocation enables each unit to transmit its voice information without
interference from other transmitting units. Transmission from a unit or base
station is accommodated in time-slot lengths of 15 milliseconds and frame
lengths of 60 milliseconds. The TDMA technique requires sophisticated
algorithms and a digital signal processor (DSP) to perform voice
compressions/decompressions and RF modulation/demodulation.

Voice Compression Technology

Voice is converted into a digital bit stream by sampling the voice at a high rate
and converting the samples into numbers, which are represented by bits.

Voice compression reduces the number of bits per second while maintaining the
voice at an acceptable quality level. The MTH800 uses a coding technique called
ACELP (Algebraic Code Excited Linear Prediction). The compressed voice-data
bits modulate the RF signal.

3 - 2 MTH800 TETRA Handportable Terminal / Basic Service Manual Description

Description

Transceiver Description

All the terminal circuitry is contained in the Digital/RF Board and the keypad
board. The Digital/RF board is divided into the following sections: digital,
frequency generating, transmitter, and receiver.

Digital Section Description

The digital section includes the Patriot IC that consists of the Mcore risk machine
and the Digital Signal Processor (DSP).

The Mcore is the controller of the Digital/RF Board. It controls the operation of the
transmitter, receiver, audio, and synthesizer integrated circuits located in the RF
section. It communicates with the keypad and display.

The Digital Signal Processor (DSP) performs modulation and de-modulation
functions for the terminal. It also performs Forward Error Correction and other
correction algorithms for overcoming channel errors and ACELP speech coding.
It carries out linear 10-bit analog to digital conversions, audio filtering, and level
amplification for the microphone audio input and the received audio output.

The power and audio section is based on the GCAP III and includes power
supplies, 13-bit CODEC, audio routing, microphone and ear piece amplifiers. A
audio power amplifier is used for the loud speaker.

Transmitter Path Description

The transmitter circuitry includes a linear class AB Power Amplifier (PA) for the
linear modulation of the MTH800. It includes a cartesian feedback loop to
enhance its transmitter linearity and reduced splattering power into adjacent
channels.

The transmitter path consists of a cartesian feedback loop that contains the
forward and loop feedback paths.

The forward path includes the JAVELIN IC, BALUN, Attenuator, Power Amplifier
and Isolator.

The loop feedback path includes the directional coupler, attenuator, BALUN, and
JAVELIN IC.

Description MTH800 TETRA Handportable Terminal / Basic Service Manual 3 - 3

The cartesian Feedback output power passes to the antenna through the
Isolator, Antenna Switch, Harmonic Filter and Duplexer.

Receiver Path Description

The receiver section in MTH800 is based on the novel DCR (Direct Conversion)
technology, the main concept of this technology is down converting of the RF
signal directly into a base band signal, skipping the intermediate stage of IF
signal.

The receiver path includes the Antenna Switch, Limiter, 10dB Step Attenuator,
Tunable Filter, LNA integrated with 28dB Step Attenuator and 40dB of AGC
continuous attenuation, Pre-selector Band Pass Filter, Balun, Half-Life Mixer, 1­pole filter, and the Tomahawk IC which consists of all the base band receive
chain.

Frequency Generating Section Description

The frequency generating section provides description of the following main
components: Tomahawk IC fractional-N Synthesizer, Escort synthesizer,
Reference oscillator, Main VCO, Tx VCO and buffer.

Global Positioning System (GPS) Section Description

The GPS section includes the following main components: Duplexer, Front filter,
LNA, Post Filter, Instant GSCi-5000 IC, RTC, and TCXO.

The GPS in the MTH800 is based on the SIRF GSCi-5000 IC, which comprises a
standalone ROM-based multimode GPS receiver in a single chip BGA Package.

CHAPTER 6

MAINTENANCE

Preventive Maintenance

This TETRA Handportable Terminal does not require a scheduled preventive
maintenance program. However, periodic visual inspection is recommended.

Inspection

Inspect the terminal’s external surfaces. A detailed inspection of interior circuitry
is not needed or recommended.

Cleaning

The following procedures describe the recommended cleaning agents and
methods to be used when cleaning the external and internal surfaces of the
radio. External surfaces should be cleaned whenever a periodic visual inspection
reveals the presence of smudges, compound, or grime. Internal surfaces (circuit
boards and components) should be cleaned only when the radio is disassembled
for servicing or repair.

The only recommended agent for cleaning external radio surfaces is a 0.5%
solution (one teaspoon of detergent per gallon of water) of mild dishwashing
detergent in water. The internal surfaces should be cleaned only with isopropyl
alcohol (100% by volume).

NOTE:

Internal surfaces should be cleaned only when the radio is disassembled
for service or repair.

Take care to clean the bottom connector frequently and particularly prior
to the programming procedure e.g. with a soft brush (do not use fluids).

The effects of certain chemicals and their
vapors can have harmful results on certain
plastics. Avoid using aerosol sprays, tuner
cleaners, and other chemicals

.

6 - 2 MTH800 TETRA Handportable Terminal / Basic Service Manual MAINTENANCE

Cleaning External Plastic Surfaces

Apply the 0.5% detergent-water solution sparingly with a stiff, non-metallic, short­bristled brush to work all loose dirt away from the radio. Use a soft, absorbent,
lintless cloth or tissue to remove the solution and dry the radio. Make sure that no
water remains entrapped near the connectors, cracks, or crevices.

Cleaning Internal Circuit Boards and Components

Isopropyl alcohol (100%) may be applied with a stiff, non-metallic, short-bristled
brush to dislodge embedded or caked materials located in hard-to-reach areas.
The brush stroke should direct the dislodged material out and away from the
inside of the radio. Make sure that controls or tunable components are not
soaked with alcohol. Do not use high-pressure air to hasten the drying process
since this could cause the liquid to collect in unwanted places. After completing of
the cleaning process, use a soft, absorbent, lintless cloth to dry the area. Do not
brush or apply any isopropyl alcohol to the frame, front cover, or back cover.

NOTE:

Always use a fresh supply of alcohol and a clean container to prevent
contamination by dissolved material (from previous usage).

Safe Handling of CMOS Devices

Complementary metal-oxide semiconductor (CMOS) devices are used in the
terminal. While the attributes of CMOS devices are many, their characteristics
make them susceptible to damage by electrostatic or high voltage charges.
Damage can be latent, resulting in failure occurring weeks or months later.
Therefore, special precautions must be taken to prevent device damage during
disassembly, troubleshooting, and repair. The following handling precautions are
mandatory for CMOS circuits, and are especially important in low humidity
conditions.

• All CMOS devices must be stored or transported in conductive material so that

all exposed leads are shorted together. CMOS devices must not be inserted
into conventional plastic “snow” or plastic trays of the type that are used for
storage or transportation of other semiconductor devices.

• All CMOS devices must be placed on a grounded bench surface and the

technician must also be grounded before handling the devices. This is done
most effectively by having the technician wear a conductive wrist strap in
series with a 100kW resistor to ground.

• Do not wear nylon clothing while handling CMOS circuits.

• Do not insert or remove CMOS devices with power applied. Check all power

supplies to be used for testing CMOS devices and be certain there are no
voltage transients present.

• When straightening CMOS device leads, provide ground straps for the

apparatus used.

• When soldering, use a grounded soldering iron.

• All power must be turned off in a system before printed circuit boards

containing CMOS devices are inserted, removed, or soldered.

MAINTENANCE MTH800 TETRA Handportable Terminal / Basic Service Manual 6 - 3

Pre-baking of Integrated Circuits

Electronic components are generally coated with plastic material which has the
nature of not being waterproof. If kept unsealed, the components can absorb
humidity. When soldered to the board (especially with reflow techniques), the
sudden change in temperature can cause fissure or crack which can result in
malfunction or damage.

To avoid this problem, these moisture sensitive components (MS) should be
stored and shipped in a sealed wrapping (dry pack). Processing is not required
only with “dry components” when an uninterrupted dry storage can be
guaranteed, otherwise the components have to be pre-baked.

If a reflow procedure takes place close to MS components, the whole board
must be pre-baked.

Refer to the table below.

Baking Precautions for TETRA Power Amplifiers (PAs)

PAs in an open reel after baking should be used within 168 hours. After 168

hours the PAs must not be used until baked again. Because this is quite a short time,
use at least two reels for each build: one on the machine, and the other still in baking.
After 168 hours the reel on the machine should be replaced with the freshly baked
reel. It is recommended to order a sufficient reserve of PAs, so that at least two reels
will be available in each build.

In addition, please note the following very important precautions that must be

observed when baking TETRA PAs before builds:

6 - 4 MTH800 TETRA Handportable Terminal / Basic Service Manual MAINTENANCE

• Correct baking (needed only if the reel has been opened) procedure is at

minimum

8 HOURS IN 125 DEGREES.

• It is ABSOLUTELY FORBIDDEN to bake at temperature above 125 degrees.

• Please note also that reels that have not been opened (still in vacuum) do not

need baking.

• When this part is replaced manually, it should be pressed to the PCB during the

soldering.
