9 TIME-OUT TIMER (TOT)

Time-out Timer (TOT) is used to restrict the continuous
transmission time.
This function prevents a user from occupying a channel
for a long period of time when the channel is shared with
other users. The transceiver stops transmitting when the
transceiver is continuously transmitting longer than the
configured time.
The Time-out Timer can be configured for each zone.
The operation of this function varies between
Conventional Group and Trunking System (TK-3173
only).
9.1

Conventional Group

The following timers relevant to Time-out Timer functions
can be configured in Conventional Group:
•

Time-out Timer

•

TOT Pre-alert

•

TOT Rekey Time

•

TOT Reset Time

9.1.1 Time-out Timer
Time-out Timer (TOT) is used to restrict the continuous
transmission time.
Time-out Timer can be configured by using
KPG-101D.
Note: Time-out Timer does not activate in Emergency Mode.
Configuration using KPG-101D
• Configuring the continuous transmission time for
each zone (Refer to FPRG 6.2.7 Time-out Timer
(TOT).)
9.1.2 TOT Pre-alert
The transceiver emits the TOT Pre-alert to notify a user
that the transmission is going to be terminated by the
Time-out Timer. The transceiver emits the TOT Pre-alert
when the remaining time of TOT is decreased to the
duration configured for TOT Pre-alert time.
The timing to emit the TOT Pre-alert tone before the TOT
terminates the transmission can be configured by using
KPG-101D.
Note: The transceiver emits the TOT Pre-alert tone only when the
transceiver is transmitting. This tone does not sound while
the transceiver pauses transmitting within the TOT Reset
Time. (Refer to 9.1.4 TOT Reset Time on page 31.)
FUNC (K)/Ver. 1.01
Configuration using KPG-101D
• Configuring the TOT Pre-alert Tone (Refer to
FPRG 6.2.8 TOT Pre-alert.)
9.1.3 TOT Rekey Time
The function is used to configure the duration of time from
when the Time-out Timer terminates the transmission to
when the transceiver starts transmitting again. This
function is used to temporarily restrict the transmission
when a user occupies the repeater or the channel for a
long time.
The TOT Rekey Time can be configured by using KPG-
101D.
Note:
The TOT Rekey Time is reset and transmission is possible after
the transceiver is turned ON or OFF while the TOT Rekey Time
is counting down.
When a CH/GID is changed using the CH/GID Up or CH/GID
Down key while the TOT Rekey Timer is counting down, the
timer is reset.
Configuration using KPG-101D
• Configuring the TOT Rekey Time (Refer to FPRG
6.2.9 TOT Rekey Time.)
9.1.4 TOT Reset Time
The TOT Reset Time is the period to reset the
Time-out Timer.
When the transceiver transmits while the TOT Reset
Time is counting down, the transceiver treats the
transmission as a continuation of the previous
transmission. This function prevents a user from
occupying a channel for a long time by transmitting
intermittently.
The TOT Reset Time can be configured by using
KPG-101D.
Note: When a CH/GID is changed using the CH/GID Up or
CH/GID Down key while the TOT Reset Timer is counting
down, the timer is reset.
Configuration using KPG-101D
• Configuring the TOT Reset Time (Refer to FPRG
6.2.10 TOT Reset Time.)
