OPERATING FEATURES
4) Battery Warning
This transceiver has a battery warning feature. If low voltage is detected during transmission, the transceiver warns you by a flashing red "LED".
When the voltage is detected to be even lower during transmission, the transceiver stops transmission and warns you by a flashing red "LED" and a beep.
Please notice "indication" for the battery exchange, charging time by flashing red LED and beep.
5) "TOT" Pre-Alert
The transceiver has a "TOT"
"TOT" will expire when the selected time passes from the TOT
6) "TOT" Re-Key Time
The transceiver has a "TOT"
7) "TOT" Reset Time
The transceiver has a "TOT" reset timer. This timer is the minimum wait time allowed during a transmission that will reset the "TOT" count.
"TOT" reset time causes the "TOT" to continue even after the PTT is released, unless the "TOT" reset timer has expired.
8)OST (Operator Selectable Tone) (TK-270G K types only)
The transceiver is capable of having the "OST" function and 16 tone pairs (QT/DQT) with a max
9) Clear to Transpond
The transceiver waits for an acknowledment signal until the channel free.
This feature ensures the acknowledment signal is receive by another party.
10) Battery Save
This is the automatic battery saver during standby mode operation. The receiver circuit is turned on and off to conserve the battery life.
6. Option Signalling (DTMF/2 tone)
It is possible to use individual call, group call, DBD (Dead Beat Disable). Note : DBD is only DTMF
Preset operation is triggered when there is a match with Option Signaling.
When Option Signaling matches on a Group Channel where it is set to Yes, the Option Signaling display flashes and Option Signaling is canceled. Settings after this will cause "Transpond" or "Alert" to sound.
Setting the Selective Call Alert LED will cause the LED to start flashing orange.
Mute or Unmute is triggered by the ID/QT/DQT/Carrier when option signaling matches (when Option Signal is deactivated by a transmission).
AND/OR
Option Signaling match conditions can be selected with AND/OR logic.
| Alert/Transpond | AF Mute Open |
AND | Triggers at match with QT/ | Triggers at match with QT/ |
| DQT/ID+DTMF(2tone);Opt | DQT/ID+DTMF(2tone);Opt |
OR | Triggers at match with QT | Triggers only for match with |
| /DQT/ID+DTMF(2tone) ; Opt | QT/DQT/ID;Signaling |
Even if set as OR, there is no Alert/Transpond just with DTMF.
Even if set as OR, AF mute cannot be canceled just by a match with DTMF.
In conventional channels not set with QT/DQT, signaling is a match just by receiving the carrier.
Auto Reset
When Option Signaling matches on a Group channel where it is set to Yes, Option Signaling is canceled when it matches a group channel set to Yes.
After Option Signaling matches, Option Signaling can automatically Reset after a specified time.
Dead Beat Disable
When the D.B.D (Dead Beat Disable) code matches, a preset operation is performed.
When D.B.D matches on all group channels regardless of whether Option Signaling = Yes/No, then TX Inhibit or TX RX Inhibit is activated by the settings performed afterwards. D.B.D is canceled when the D.B.D. code + "#" is received.
Transpond is always activated when the D.B.D code matches. Alert is not output. An Option Signaling match is not displayed.
