MISCELLANEOUS INFORMATION

the side upward and rotate the pack counterclockwise (when viewed from the bottom). To install a pack, insert it in the socket and rotate it clock- wise until it locks in place. A new pack must be charged before use.

Battery Operating Time

Typical operating time before recharging is required depends on what model of transceiver you have and also how you use it. The 8560/70 models have fixed power output and the 8565 model has user-selectable high and low power outputs. With the following times, it is also assumed that 90% of the time is spent in the standby mode (receiving, audio muted), 5% in the receive mode (audio enabled), and 5% in the transmit mode. If more time is spent in the receive or transmit modes, the time

varies accordingly. Recharging is required when appears in the display and a beep sounds when the push-to-talk switch is released. Do not regularly use a pack until the transceiver becomes totally inoperative because this can shorten battery life.

Transceiver		1400 mAH Battery (P.N. 587-8565-162)
8560/70 (fixed output)			14 hrs
8565	(low power selected)		10.5 hrs
8565	(high power selected)		8.5 hrs

Recharging

The battery pack can be recharged while it is attached to the trans- ceiver or it can be removed and recharged. Charging time is somewhat longer if the transceiver is left on while recharging, especially when using the trickle charger. Approximate charge times with the various chargers are shown below. It is assumed that the battery is discharged to the point where the low-battery indication appears. When the rapid and vehicular chargers are used, a steady or red indicator indicates charging in the rapid mode and a flashing or green indicator indicates charging in the trickle rate and an almost fully charged battery.
