You can choose to set one of the following 3 operations when the channel is switched during
scanning:
1. No operation.
2. Scan the current channel: The scanning will pause on the current channel, and the pause time
will be the Dropout Delay Time. However, this channel will not be added to the scan list.
3. Exit scanning.

Power-on scanning: If this function is enabled, the radio will start scanning after the radio
power is turned on.
7. Auxiliary Functions
7.1 Time-Out Timer (TOT)
1) TOT Function
The time-out-timer can prevent the user from continuously talking overlong and prevent the
radio from heating due to continuous transmitting.
If you continuously transmit longer than the preset TOT time, the radio will make an alert tone
and stop transmitting. To stop the warning tone, release the PTT button.
2) TOT Pre-alert
The radio will make an alert tone in advance before the TOT terminates the transmission. After
the alert tone, when the time of transmission exceeds the preset time, the TOT timer will act.
3) TOT Rekey Time
A period in which the radio is forbidden to transmit after its overtime activity.
During the period, if the PTT button is pressed, an alert tone will be sounded, and the
transmission is forbidden.
4) TOT Reset Time
The time delay from releasing the PTT button to the resetting of the timer is limited.
The countdown will go on if the time after releasing the PTT key is shorter than the reset time.
7.2 Busy Channel Lockout (BCL)
If the channel on which a user attempts to transmit is being used by another party, BCL
function restricts the transmission in order to avoid interfering with the other parties'
communication, and the radio will make an alert tone, and returns to the receiving state.
7.3 Battery Saving
The battery saving function can reduce power consumption of the radio when no signal is
received and no operation is conducted (no button is pressed and no knob is turned).
If the radio hasn't receive any signal or no operation is being conducted for 16 seconds, the
radio will enter Battery Saving Mode. When a signal is received or any operation occurs, the radio
will exit the Battery Saving Mode automatically.
