Lithium Battery - Kenwood TS-670 Instruction Manual

@ 4-18 POWER SUPPLY CAPACITY OF
AUTOMOBILE Battery Capacity
The power system of a motor vehicle is comprised of a bat-
tery and an alternator (which generates power while the
engine is running) to supply current to loads or to charge
the battery.
Since the transceiver draws high current during transmit,
care should be excersised so the power system is not
overloaded. When using the transceiver, the following
points should be observed from the viewpoint of battery
maintenance:
(1) Turn the transceiver OFF when the lights, heater,
wipers and other high-draw accessories are used.
(2) Avoid transceiver operation when the engine is not
running.
(3) If necessary, use an ammeter and/or a voltmeter to
check battery condition.
NOTES:
The standard supply voltage of TS-670 is 13.8 V. The
standard current is about 4 A at transmission and about
1 A at reception.
Use of a voltage outside the 12 - 16 V range may cause
reduced performance and or misoperation.
Avoid using such a voltage as a power supply.
@ 4-19 MICROPROCESSOR BACK-UP
LITHIUM
BATTERY
The TS-670
has a built-in lithium
battery as a backup
power supply for the memory.
The life of this battery is
estimated at 5 years. When the frequency display is reset
by turning on and off the power switch (50.000.0 Hz,
USB), it indicates expiration of the battery life. Replace the
battery in this case.
@ 4-20 OPTIONAL 10 Hz DISPLAY
RESULUTION If you would like 10 Hz resolution instead of the supplied
100 Hz display resolution, cut D-55 as shown on the Con-
trol unit.
