Before you operate the transceiver outside using a battery pack, it is important to
know how long the battery pack will last. The operating times listed in the table
below are measured under the following cyclic conditions:
TX: 6 seconds, RX: 6 seconds, Stand-by: 48 seconds
We recommend you carry extra battery packs with you, in case the battery pack
becomes depleted.
