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 the current settings not being saved
in memory.
Recharging
Recharging is required when the icon appears in the lower
part of the display. In addition, the amber low-battery indicator on the top
panel may light and a tone may sound when this condition initially occurs
and whenever the PTT switch is released. Refer to “Low Battery Indica-
tion” on page 18 for more information.
The pack can be recharged while still on the transceiver or it can be
charged separately. To remove the battery pack from the transceiver,
press the spring-loaded release button on the side upward 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.
