7.5
Reducing Battery Consumption (Battery Saver)
Supported Models: Portable
Battery Saver allows the transceiver to reduce power consumption by receiving intermittently.
The transceiver receives intermittently when there is no carrier and no key is pressed for 5 sec or more, or when the
transceiver is in the following states:
0
Analog Conventional channel
When
there is a carrier, but the QT tone or DQT code does not match the tone or code preconfigured for the transceiver
and no key is pressed for 5 sec or more
0
P25 Conventional channel
When there is a carrier, but the NAC (Network Access Code) does not match the code preconfigured for the transceiver
and no key is pressed for 5 sec or more
0
NXDN Conventional channel
When there is a carrier, but the RAN (Radio Access Number) does not match the number preconfigured for the transceiver
and no key is pressed for 5 sec or more
0
DMR Conventional channel
When there is a carrier, but the Color Code does not match the code preconfigured for the transceiver and no key is
pressed for 5 sec or more
Extension of the intervals for intermittent reception may reduce the battery consumption; however, interruptions to
introductory parts of received audio may occur. To use Battery Saver effectively, there are systemic issues to consider, for
instance, the duration from when the transceiver starts transmitting until the transceiver starts sending audio.
Intervals for intermittent reception are as follows.

Battery Saver is activated only in an Analog Conventional system, P25 Conventional system and NXDN Conventional
system.
0
Battery Saver is not activated while the transceiver is scanning.
