Loud Speech (Simplex)
24. Under some circumstances telephone-style communication will not be possible,
e.g. noisy environment, wearing of protective headgear. The high volume levels
required for listening would inhibit operation because of feedback. In this situation,
simplex operation is desirable. When calling another transceiver, only simplex
operation is possible.
25. To select loud speech, press twice (the message "Use PTT" is displayed). To
speak, depress the PTT key. Release the PTT switch after speaking, to listen to the
other party. Subsequent presses of
toggles the transceiver between telephone
mode (the message "On" is displayed) and loud speech mode (message "Use PTT" is
displayed).
New Status
26. Each call is automatically given new status when first received. New status is removed
by cancelling the alert or reviewing the call from memory. If the alert is left uncancelled
then the prompt "x new messages" appears on the display showing the number of
messages with new status (where
x is a integer from 1 to 5). Each message must be
viewed in full for new status to be removed.
Cancelling Alerts
27. Cancel the alert by pressing the button. The beep and LED alert cease but the
message is replayed from the beginning.
Escalating Alert
28. The escalating alert has three stages - the first two lasting 4 seconds each and the last
one 8s, 16s, 32s or continuous. The stages are as follows:
Stage 1: LED, flashing beep pattern.
Stage 2: LED, low volume beep pattern.
Stage 3: LED, full volume beep pattern.
29. The option for Escalating Alert is programmed into the EEPROM. However, the
escalating alert and the Mute mode are overridden by beep code 5 (triple pip) and beep
code 8 (continuous pip). They cause the alert to be on full volume for the whole of the
programmed alert duration.
