use.
To replace the covers ESD protection must be applied.
All electronic parts of the product are susceptible to ESD.
Resistors, too, can be damaged by static electricity discharge.
All ESD sensitive parts must be packed in metallized protective bags during shipping and handling outside any ESD
Protected Area (EPA).
Every repair action involving opening the product or handling the product components must be done under ESD
protection.
ESD protected spare part packages MUST NOT be
opened/closed out of an ESD Protected Area.
For more information and local requirements about ESD
protection and ESD Protected Area, contact your local
Nokia After Market Services representative.
Note that a new battery's full performance is achieved only after two or three
complete charge and discharge cycles.
The battery can be charged and discharged hundreds of times but it will
eventually wear out. When the operating time (talk-time and standby time) is
noticeably shorter than normal, it is time to buy a new battery.
Use only batteries approved by the mobile terminal manufacturer and recharge
the battery only with the chargers approved by the manufacturer. Unplug the
charger when not in use. Do not leave the battery connected to a charger for
longer than a week, since overcharging may shorten its lifetime. If left unused
a fully charged battery will discharge itself over time.
Temperature extremes can affect the ability of your battery to charge.
For good operation times with Ni-Cd/NiMh batteries, discharge the battery
from time to time by leaving the product switched on until it turns itself off (or
by using the battery discharge facility of any approved accessory available for
the product). Do not attempt to discharge the battery by any other means.
Use the battery only for its intended purpose.
Never use any charger or battery which is damaged.
Do not short-circuit the battery. Accidental short-circuiting can occur when a
metallic object (coin, clip or pen) causes direct connection of the + and terminals of the battery (metal strips on the battery) for example when you
carry a spare battery in your pocket or purse. Short- circuiting the terminals
may damage the battery or the connecting object.
Leaving the battery in hot or cold places, such as in a closed car in summer or
winter conditions, will reduce the capacity and lifetime of the battery. Always
try to keep the battery between 15°C and 25°C (59°F and 77°F). A mobile
terminal with a hot or cold battery may temporarily not work, even when the
battery is fully charged. Batteries' performance is particularly limited in
temperatures well below freezing.
Do not dispose of batteries in a fire.
Dispose of batteries according to local regulations (e.g. recycling). Do not
dispose as household waste.
The mobile terminal is a product of superior design and craftsmanship and
should be treated with care. The suggestions below will help you to fulfill any
warranty obligations and to enjoy this product for many years.
Keep the mobile terminal and all its parts and accessories out of the reach of
small children.
Keep the mobile terminal dry. Precipitation, humidity and all types of liquids or
moisture can contain minerals that will corrode electronic circuits.
Do not use or store the mobile terminal in dusty, dirty areas. Its moving parts
can be damaged.
Do not store the mobile terminal in hot areas. High temperatures can shorten
the life of electronic devices, damage batteries, and warp or melt certain
plastics.
Do not store the mobile terminal in cold areas. When it warms up (to its
normal temperature), moisture can form inside, which may damage electronic
circuit boards.
Do not drop, knock or shake the mobile terminal. Rough handling can break
internal circuit boards.
Do not use harsh chemicals, cleaning solvents, or strong detergents to clean
the mobile terminal.
Do not paint the mobile terminal. Paint can clog the moving parts and prevent
proper operation.
Use only the supplied or an approved replacement antenna. Unauthorized
antennas, modifications or attachments could damage the mobile terminal and
may violate regulations governing radio devices.
All of the above suggestions apply equally to the product, battery, charger or
any accessory.
Our policy is of continuous development; details of all technical modifications
will be included with service bulletins.

Nokia Customer CareAntenna Description and Troubleshooting
Damaged RF Feed or Ground Pins
The main antenna and the GPS antenna have pins (spring clips) that must properly touch
the PWB.
•If the main antenna’s RF feed pin does not touch the PWB, the antenna gain
degrades by more than 25 dB and the GPS antenna is detuned.
•If the ground pin of the main antenna does not touch the PWB, the antenna gain
degrades from 5 to 10 dB and the GPS antenna is detuned.
•If the GPS antenna’s RF feed pin does not touch the PWB, then the GPS antenna
gain degrades by more than 20 dB.
•If the ground pin of the GPS antenna does not touch the PWB, the GPS antenna
gain may degrade by more than 5 dB.

•If either the RF pin or ground pin springs appear damaged, replace the internal
antenna.
Damaged IHF Speaker Pogo Pins
In Figure 3, the two pogo pins on the back of the internal antenna must properly touch
the PWB. If not, the PCS gain of the internal antenna can degrade by 2 dB and no audio
will emit from the speaker.
Wrong Internal Antenna Installed
The internal antenna is mechanically similar to the one used in the 2112 mobile terminal.
Following are important differences between these antennas:
2115i/2116/2116i (RH-66)
Antenna Description and Troubleshooting
•The 2115i/2116/2116i includes a GPS antenna. The 2112 does not.
Note: GPS is functional only in the 2115i and 2116i.
•The main radiators for the 2115i/2116/2116i include markings that begin with an
“F”. The 2112 markings begin with a “C”.
2115i/2116/2116i
GPS antenna
Figure 4: Top view of the 2115i/2116/2116i (left) and 2112 (right) internal antennas
Installing the 2112 antenna in the 2115i/2116/2116i is not compliant with Nokia’s FCC
submission because the 2112:
2112
•Uses a single-band (no PCS)
•Does not have a GPS antenna
•Is not tuned correctly for the 2115i/2116/2116i mechanics
•Does not make contact with the feed/ground pads on the PWB
Use the following to troubleshoot the internal antenna:
•If the wrong antenna is installed, install the correct one.
•If the slot in the radiator has a significantly different shape, install the correct
internal antenna. Be aware that the shape of the slot can vary slightly. The length
of the horizontal slot and the opening of the vertical slot can vary by a few
millimeters because the antennas are tuned for each batch of plastic frames.
•If there are other obvious damages to the radiator (e.g., dents and corrosion),
replace the antenna.
•If the pin is stuck or has excessive friction with the plastic tube/guiding feature,
the spring will not work properly. Replace the antenna.

RF Connector Failure
The RF connector fails when it does not properly connect the RF input to the RF output.
If this happens the antenna gain degrades by 25 dB. Check this by testing for DC
conductivity between the RF input and RF output of the RF connector.
Note: Perform the DC conductivity test without a cable attached to the RF
connector. Because the RF connector is also a switch, the RF output is disconnected
from the RF input when a cable is inserted into the RF connector.

RUIM Card Flap Grounding
The RUIM card flap must be grounded to the RF shield with a conductive sticker.
Disassembling the RF shield from the chassis damages the sticker. You must remove the
sticker to change the antenna module or the RUIM card flap. If the sticker is damaged or
missing, then the radiated sensitivity at maximum power could be reduced by 1-2 dB.
•If the conductive sticker is missing or ripped, replace it.
•If the RF shield is replaced, install new labels (type labels) and a new conductive
sticker. If the conductive sticker is located underneath other labels, then it may
be necessary to replace all other labels as well.

Antenna Description and Troubleshooting
Testing the CDMA Antenna
Calibration Factors
Use the MJF-28 Docking Station Adapter to define the CPL-8 Antenna Coupler
calibration numbers. Obtain the calibration numbers by utilizing a mobile terminal with
known RF and antenna performance. Each test adapter should only require a single
calibration on PCS1900 and GPS bands at used test frequencies. Additional calibrations
should only be needed if the test adapter is substantially modified (reassembled, changed
parts, dropped, etc.).
Calibration Factor for PCS1900 Frequency
Use a call box to turn on the mobile terminal’s transmitter with a known output power
and antenna performance at the maximum output power (all bits up). Measure the
transmitted power on the RF connector and through a coupler at CDMA PCS channel
1175. Use the difference between the transmitted and received powers as the calibration
number (path loss on Cell band including coupler, cable, and attenuator path losses) for
the coupler on Cell band.
The nominal value for power measured at the RF connector is 23 dBm. The coupler path
loss is normally from 17 to 18 dB at the PCS band. If you use a 10 dB attenuator and a
cable with ~1 dB loss, the total path loss is from 28 to 29 dB and the measured power
should be from -5 to -6 dBm [23 dBm - (28…29 dB)]. However, you must measure path
loss separately for every coupler because path losses vary depending on the setup, cables,
and attenuator.
Measurement Procedure
Use the following measurement procedures for 800/1900 mobile terminals:
1. Place the mobile terminal in the MJF-28 Docking Station Adapter with the
display facing upward and its whip retracted.
2. Turn on the mobile terminal's transmitter at the PCS band on CDMA mode
channel 1175 at maximum output power (nominal 23 dBm at RF connector).
3. Measure the RF power with a CPL-8 Antenna Coupler. This represents the internal
antenna to RF coupler measurement.
4. Turn the mobile terminal's transmitter off.
The CDMA antenna test fails if the measured power is outside the test limits.

Testing the GPS Antenna (2115i/2116i)
Calibration Factor for GPS
In GPS test mode 3, the GPS receiver is fed with a CW signal. The GPS receiver should
report C/No ratio of 35 dBHz with a -110 dBm signal level on the RF connector
(-110 dBm + cable loss) at signal generator output. The reported C/No figure is recorded
with the signal fed to the RF connector. The C/No value is read with a coupler engaged.
Increase the GPS signal level until the same C/No value is recorded. Use the difference
between the CW signal levels at the generator as the calibration number (path loss on
GPS band including coupler, cable, and attenuator losses).
The nominal coupler path loss at GPS band is 14 to 17 dB. If you use a 10 dB attenuator
and cable with 1 dB loss, the total path loss is 25 to 28 dB. The signal level at generator
output must be -85 to -82 dBm [-110 dBm -(-25 dB to -28 dB)]. However, the path loss
has to be measured separately for every coupler because the path losses vary depending
on the setup, cables, and attenuator.
Measurement Procedure
Use the following steps as a measurement procedure for the GPS Antenna:
1. Place the mobile terminal in the MJF-28 Docking Station Adapter with the
display facing up and the whip retracted.
2. Turn on the CW signal generator (with power -110 dBm + coupler, cable, and
attenuator path loss at GPS band) fed to the RF coupler.
3. Read the reported C/No figure with the test mode 3 three to four times to see if
it is stable.
The GPS antenna test fails if the C/No value is outside the test limits.

Nokia Customer CareBaseband Description and Troubleshooting
Introduction
The mobile terminal uses a CDMA tri-mode engine (AMPS/800/1900) with a DCT4
baseband consisting of three ASICs:
•Universal Energy Management cost reduction (UEMC)
•Universal Phone Processor (UPP) - UPP8Mv4.2
•8MB flash memory with 1 MB of RAM memory
The baseband architecture supports a power-saving function called sleep mode. Sleep
mode shuts off the voltage-controlled temperature-compensated crystal oscillator
(VCTCXO), which is used as the system clock source for both the RF and the baseband.
During sleep mode, the system runs from a 32 kHz crystal and all the RF regulators
(VR1A, VR1B, VR2—VR7) are off. The sleep time is determined by network parameters.
Sleep mode is entered when both the Master Control Unit (MCU) and the Digital Signal
Processor (DSP) are in standby mode and the normal VCTCXO clock is switched off. The
mobile terminal is awakened by a timer running from this 32 kHz clock supply. The period
of the sleep/wake up cycle (slotted cycle) is 1.28N seconds, where N= 0, 1, 2, depending
on the slot cycle index.
The mobile terminal supports standard Nokia 2-wire and 3-wire chargers (ACP-x and
LCH-x). However, the 3-wire chargers are treated as 2-wire chargers. The PWM control
signal for controlling the 3-wire charger is ignored. The UEMC and energy management
software control charging.
A BL-6C (1070 mAh) lithium-ion battery is used as the main power source.
