Typical operating time before recharging is required is 7.3 hours.
This assumes that the transceiver is transmitting at high power 5% of the
time, receiving and producing audio 5% of the time, and in the standby
mode (receive with audio muted) 90% of the time. If the low-power mode
is selected or different times are spent in these modes, operating time
varies accordingly. The charge of the battery and ambient temperature
also affect operating time.
NOTE: Be sure to turn transceiver power off before removing the battery
pack. Failure to do so may result in current settings not being saved in
memory.
Recharging
Recharging is required when the icon is displayed as
described on page 23. To remove the battery pack from the transceiver for
recharging (see next section), press the spring-loaded release button on
the bottom and slide the battery off. A new battery pack must be charged
before use.
Battery Care
One cause of shortened battery life is repeated deep discharge.
Therefore, it is recommended that the battery be recharged as soon as
practical after the low-battery indication appears (see preceding informa-
tion). Do not continue using the transceiver until the battery is completely
discharged. Another cause of reduced battery life is operation at tempera-
ture extremes. It is also good practice not to regularly leave a pack in the
charger for extended periods after it is completely charged.
It is possible that the pack could develop a characteristic called
“memory” although these packs are designed to minimize that problem.
When a pack has this problem, it acts as if it is totally discharged even
though it has greater capacity. This can be caused by discharging a pack
only slightly before recharging, charging at too high a temperature, or
extended storage. If a pack develops this problem, it can usually be
corrected by performing three discharge/charge cycles.
