SAFETY INFORMATION
The operator of any mobile radio should be aware of certain
hazards common to the operation of vehicular radio transmissions. A
list of several possible hazards is given:
1. Explosive Atmospheres - Just as it is dangerous to fuel a vehicle
with the motor running, similar hazards exist when operating a
mobile radio, be sure to turn the radio off while fueling the
vehicle. Do not carry containers of fuel in the trunk of the vehicle
if the radio is mounted in the trunk.
2. Interference to Vehicular Electronics Systems - Electronic fuel
injection systems, electronic anti-skid braking systems, electronic
cruise control systems, etc., are typical electronic systems that may
malfunction due to the lack of protection from radio frequency
energy present when transmitting. If the vehicle contains such
equipment, consult the dealer and enlist his aid in determining the
expected performance of electronic circuits when the radio is
transmitting.
4
3. Dynamite Blasting Caps - Dynamite blasting caps may be caused
to explode by operating a radio within 500 feet of the blasting
caps. Always obey the "Turn Off Two-Way Radios" signs
posted where dynamite is being used.
When transporting blasting caps in your vehicle:
a. Carry the blasting caps in a closed metal box with a soft
lining.
b. Leave the radio OFF whenever the blasting caps are
being put into or removed from the vehicle.
4. Radio Frequency Energy - To prevent burns or related physical
injury from radio frequency energy, do not operate the transmitter
when anyone outside of the vehicle is within two feet of the
antenna.
5. Liquefied Petroleum (LP) Gas Powered Vehicles - Mobile radio
installations in vehicles powered by liquefied petroleum gas with
the LP gas container in the trunk or other sealed-off space within
the interior of the vehicle must conform to the National Fire
Protection Association standard (NFPA) 58 requiring:
a. The space containing the radio equipment shall be
isolated by a seal from the space containing the LP gas
container and its fittings.
b. Outside filling connections shall be used for the LP gas
container.
c. The LP gas container shall be vented to the outside of the
vehicle.
CAUTION
Before jump starting or changing the vehicle battery, it is strongly
suggested that the 3A fuse located in the Yellow lead (IGN A+) be
removed. This will insure that the radio is protected from damage
during the battery charging process. Replace fuse when charging is
completed.

SAFE DRIVING RECOMMENDATIONS FOR
USERS OF MOBILE RADIOS RECOMMENDED BY
AAA
• Read the literature on the safe operation of the radio.
• Keep both hands on the steering wheel and the microphone in
its hanger whenever the vehicle is in motion.
• Place calls only when vehicle is stopped.
• When talking from a moving vehicle is unavoidable, drive in
the slower lane. Keep conversations brief.
• If a conversation requires taking notes or complex thought,
stop the vehicle in a safe place and continue the call.
• Whenever using a mobile radio exercise caution.
OPERATING RULES AND REGULATIONS
Two-way FM radio systems must be operated in accordance with
the rules and regulations of the Federal Communications Commission
(FCC). As an operator of two-way radio equipment, you must be
thoroughly familiar with the rules that apply to your particular type of
radio operation. Following these rules helps eliminate confusion,
assures the most efficient use of the existing radio channels, and
results in a smoothly functioning radio network.
When using your two-way radio, remember these rules:
1. It is a violation of FCC rules to interrupt any distress or
emergency message. As your radio operates in much the same
way as a telephone "party line", always listen to make sure
that the channel is clear before transmitting. Emergency calls
havepriority over all other messages. If someone is sending an
emergency message - such as reporting a fire or asking for
help in an accident - KEEP OFF THE AIR!
2. The use of profane or obscene language is prohibited by
Federal law.
6
3. It is against the law to send false call letters or false distress
or emergency messages. The FCC requires that you keep
conversations brief and confine them to business. To save
time, use coded messages whenever possible.
4. Using your radio to send personal messages (except in an
emergency) is a violation of FCC rules. You may send only
those messages that are essential for the operation of your
business.
5. I t is against Federal law to repeat or otherwise make known
anything you overhear on your radio. Conversations between
others sharing your channel must be regarded as confidential.
6. The FCC requires that you identify yourself a t certain specific
times by means of your call letters. Refer to the rules that
apply to your particular type of operation for the proper
procedure.
7. No changes or adjustments shall be made to the equipment
except by an authorized or certified electronic technician.
IMPORTANT
OPERATING TIPS
The following conditions tend to reduce the effective range of two-
way radios and should be avoided whenever possible:
• Operating the radio in areas of low terrain, or while under
power lines or bridges.
• Obstructions such as mountains and buildings.
In areas where transmission or reception is poor, some
improvement may be obtained by insuring that the antenna is vertical.
Under U.S. law, operation of an unlicensed radio transmitter
within the jurisdiction of the United States may be punishable by
a fine of up to $10,000, imprisonment for up to two years, or
both!
INTERCONNECT CABLE
Power Leads
The power leads of the interconnect cable supplied with the
charger must be connected to the vehicle's battery (for the Part 2 and
ORION Control Head chargers). The vehicle must have a negative-
ground electrical system. Power leads are approximately 8 feet in
length. The YELLOW (positive) lead includes a fuse holder and 5-
ampere fuse located near the battery end.
The charger can be wired to an unswitched power source so the
charger can operate when the vehicle's ignition switch is turned off.
However, if desired, the charger can be controlled by a switched power
source by running a lead to the ignition switch power (be sure to
connect this lead behind the vehicle's fuse box so that the vehicle's fuse
protection is used). The other end of this lead must be connected to the
DB-25 connector at pin 10. The power source must have adequate
current supply capability. If the switched power connections are used
the Charger's DIP switch settings must be changed as shown under,
"SETTING THE DIP SWITCHES”, to Enable Ignition A+.
If the charger is wired directly to the vehicle's battery it will be
necessary to route the power leads through the vehicle's firewall. If a n
existing hole is not conveniently located in the firewall, drill a small
hole and install an appropriately sized rubber grommet before routing
the leads through the firewall. This grommet is required to prevent
lead chaffing. Additional grommets may be required if the leads must
pass through shields or guards in the engine compartment between th e
firewall and battery. Route the leads away from high heat sources in
the engine compartment that may cause lead damage and introduce a
fire hazard. In addition, the leads should not be routed near noise
sources such as electronic ignition modules or cruise control modules.
Use appropriate lacing techniques to secure the leads away from all
moving parts.
Connect the BLACK lead to the negative power source ("NEG" or
"-" battery post) and connect the YELLOW lead to the positive power
source ("POS" or "+" battery post).

Moving a few yards in another direction or moving to a higher
elevation may also improve communication.
INTRODUCTION
The Ericsson GE M-RK Standard Vehicular Charger
(344A4616P1) and Enhanced Vehicular Charger (344A4616P2) units
can be used with both the M-RK I and M-RK II Personal radios with
swivel mount or belt clips attached. Any of the four batteries listed
below can be used with the MR-K I, or II radios and these chargers.
19A149838P1 1200 mAh
19A149838P2 1200 mAh (intrinsically safe)
344A3278P1 1700 mAh
344A3278P2 1700 mAh (intrinsically safe)
A vehicular charger enhances the operational versatility of an MRK radio in the mobile environment. See Table 1 for the features of
each unit.
The Standard Vehicular Charger (Repeater) (344A4616P1) is
designed to provide recharge of M-RK radio batteries without
provision for operation while in the charger. With this model charger,
M-RK radio operation is only possible outside of the charger. The
vehicular repeater is automatically disabled when the M-RK radio is
placed in the Charger and the unit performs the charging function.
The Charger has an ON/OFF repeater enable switch for operation with
the M-RK radio outside the Charger. Both fast and slow charge rates
are built into the charger that operate automatically based upon battery
pack voltage and temperature.
The Enhanced Vehicular Charger (344A4616P2) simultaneously
charges the M-RK's battery pack while allowing the radio to operate as
a mobile radio with an external antenna, speaker, and microphone.
The same fast and slow charge rates are provided (as in Part 1) that
depend upon the battery pack voltage and temperature conditions.
Mobile radio operation is accomplished through the use of an external
speaker, external microphone and external antenna connections. A
speaker amplifier in the charger unit provides u p to 10 watts of audio
output power to an external speaker. A volume control o n the charger
8
provides audio level adjustment for the external speaker. The MRK's
volume setting does not affect the audio level of the charger.
With the Enhanced charger, operation of the M-RK radio while
inserted in the charger is possible even though the NICAD battery is
completely discharged.
Table 1 gives feature comparisons for the two vehicular chargers
and Figure 1 shows the Front Panels of both units.

MOBILE CHARGER OPERATION
Operation of the Charger is possible in three configurations. (1)
As a standard vehicular charger and repeater control, (2) as and
Enhanced Charger providing added operational features, and (3) as an
Ehanced Charger operating via the ORION Control Head. For
operation in configuration (3) see the applicable Operator's Manual.
Standard Vehicular Charger (with Repeater) (344A4616P1)
Operation of the chargers is automatic when the M-RK personal
radio is inserted. The radio is inserted i n the charger when the battery
needs recharging. With the charger standard model, no operation of
the radio is possible while the radio battery is charging. Operation of
the radio with this model charger is done after the personal radio
battery is charged, it is removed from the charger and (normally) is
taken outside the vehicle and operated via a repeater radio. Note that
the vehicular repeater is automatically disabled when the radio is in
