CHRG (Yellow) -  Lights when radio is first inserted in 

the charger. Indicates Radio is being 
"fast" charged.

(2) ON/OFF Volume Control Switch -

This  switch powers the  radio for  operation as a mobile.
Check to assure that the UDC  LATCH KNOB is in the
"engaged" position.

(3) Option Pushbutton -

This button can be programmed for  many functions, but
factory programming causes the  same action as the M-
RK "Clear" function. (See the M-RK Operator's Manual
LBI-38732 or LBI-38733).

 (4) UDC Rotary Latch Knob -

This  knob latches the M-RK personal radio in the
charger and connects the UDC  connector to all circuits
within the charger to allow M-RK radio operation as a
mobile radio. It should always be latched when the radio
is in the charger and the vehicle is moving.

BATTERY CHARGER DETAILS

NOTE

To maximize nickel cadmium battery life, the M-RK vehicular

chargers are designed with automatic controls which limit the rapid
charging of M-RK batteries if the  internal battery temperature is
below 0

°

 C (+32

°

 F) or above +45

°

 C (+113

°

 F). The charger

indicates this high or low internal temperature condition by a yellow
LED which blinks at a slow rate.

If a slow blinking, yellow LED  is observed, the  operator must

wait  until the internal battery temperature stabilizes within the
allowable  range  before  restarting the charging procedure by
removing and re-inserting the radio into the charger.

In a vehicular application, with either high ambient temperature

inside or outside of the  vehicle, the automatic charging control will
often prevent rapid charging or limit the time of rapid charging.

In other situations, where the operator inserts and removes the

radio many times during a short period of time, the automatic control
will sense a high internal battery temperature (due to start-up rapid
charging of the battery) and will prevent further rapid charging of
the battery until the internal temperature of the battery stabilizes
within the acceptable range.

When the M-RK radio (with its battery pack) is placed in the

charger, the radio's battery pack is charged. The fast or "rapid" charge
feature, normally is applied immediately, and  is controlled by the
microprocessor circuits within the charger. The following details apply
to the battery charge feature:

Normally, when initially placed in the charger, the battery pack is
fast charged and  the yellow charge indicator glows continuously
until it is near a full charge (between 90% and 100% full charge).
At this time the charger switches to a slow or "trickle" charge rate
and  completes  the  charge. During the "trickle" charge the green
ready indicator is illuminated.
