7. Talkaround Group Call Hang Time (ms)
Sets the duration during which a radio will talk back to a received call or continue a transmitted
Talkaround Group Call using the previously received or previously transmitted digital group
ID. After expiration of the Talkaround Group Call hang timer, the radio will transmit using the TX
Contact Name (digital group) specified for this channel in CPS.
8. Talkaround Private Call Hang Time (ms)
Sets the duration the radio keeps the Talkaround Private Call setup after the user releases the
Push-to-Talk (PTT) button. This is to avoid setting up the call again each time the user presses the
PTT to transmit. During this time, other radios can still transmit since the channel is essentially idle.
After the hang timer expires, the radio transmits using the TX Contact Name specified for this
channel in CPS.
9. Access authentication
Digital radio have two working modes: normal working mode and safety working mode, these setting
only valid during repeater mode.
1 normal working mode, handheld only need to send request of “establish connection” to the repeater,
the channel will be available after connection succeed, and all the radios connected to this repeater
can communicate with each other, repeater will keep this working mode until Intentional disconnect or
beyond TOT range, this mode can make connection between radios quickly.
2, safety mode: handheld A send a request of ““establish connection” to the repeater, repeater send
this request to handheld B, the channel will be available after connection succeed, repeater reply a
confirm signal to handheld A, A and B can communicate with each other.
10. Battery Saver
●Enabling this feature causes an idle radio to automatically enter battery saver mode where it
places certain radio functions on standby. After a certain duration or when there is any user button
action, the radio returns to normal operation and checks the channel for incoming calls. If no calls
are detected, it returns to the battery saver mode. While results vary across battery chemistry and
user conditions, battery saver can deliver about a 10% improvement in battery life, but also causes a
delay in response time.
●When this feature is enabled, it is important to note that for the transmitting radios, there will be a
slight delay in call setup (in the range of milliseconds) when pressing the Push-to-Talk (PTT) button.
For the receiving radios, there may be an increase in late entry due to radios in battery saver mode
having less opportunity to properly synchronize. This may cause the radios to miss the initial second
of some audio transmissions in poor radio frequency (RF) conditions. This, however, will not be
experienced in good RF coverage. Although they are important to note, these delays are considered
minor versus the 10% improved battery life, therefore it is recommended to enable battery saver
mode for all radios.
11. Disable All LEDs
Turns off all LEDs during radio power up (except for repeater) and while radio is in use. All LEDs
are disabled including the backlight and power up LED, regardless of the backlight setting.
