TM1215 Iss. 6.0 RPR750
To change the hours repeatedly press, or press and hold the MUTE button, until the
desired hour is displayed. When this point has been reached, press the CANCEL button
and the minutes will start to flash. Press the MUTE button as before, until the desired
minutes are displayed. To complete the set-up, press the CANCEL button and the pager
will continue the switch-on sequence, starting at the address display for MK6/7 variants, or
the switch-on message for POCSAG variants.
If an incorrect time is entered, the CANCEL button may be pressed during the switch-on
sequence and the initial time-of-day screen will be re-displayed and the time may be re-
entered. To reset the time on a pager which has already been switched-on, simply turn
the pager off and on again and follow the set-up sequence. If a pager has the permanent
on option activated, reset the pager as per Section 2.4.4. and follow the time-of day set-up
sequence.
2.5.2 Call Comparator
The Call Comparator is a software programmable option, which enables the pager to
recognise calls that are a repetition of a previous call, sent within a pre-determined time
after the original call. The pager will ignore any repeated calls identified by the
comparator. The time limit can be programmed for periods of 30s, 120s and 300s after the
original call.
The exception to this will be for message calls, where the original call has not been
decoded with 100% confidence. In this case the subsequent call will be accepted and will
overwrite the original message in the pager's memory. In both cases however, a normal
alert sequence will be generated.
2.5.3 Out of Range Warning
If enabled, the Out Of Range Warning, will notify the user if the pager has not received a
valid signal for a preset time, nominally 3 minutes 30 seconds for on-site variants and 5
minutes for POCSAG variants. Combinations of alert options are available, including
visual only, audible plus visual, or either option plus vibrate.
The audible/visual option enables an out of range warning on the display for 4 seconds,
accompanied by a 2s quiet buzz (512Hz). Pagers with the audible warning enabled, will
also produce a buzz when the CANCEL button is pressed whilst the receiver is out of
range. For the visual only alert, just the message is displayed. In all cases when selected,
the vibrate option will cause several short pulses during the alert period.
After the 4s alert period, the pager will return to the quiescent mode. The range status
may be checked at any time, by using the status interrogation as described in Section
2.4.5.
2.5.4 Low Battery Warning
It is advised that this option is not enabled for use with rechargeable cells.
The battery condition is continually monitored and if a low battery voltage is sensed the
pager will continue to operate, but the battery must be changed at the earliest opportunity
(usually within the next 24hrs., depending upon system traffic levels), or continued
operation cannot be guaranteed.
