or FAIL depending on the correctness of the received
data. If you leave the TALK/BELL/MON switch in this
position when the Ranger is ringing, nothing will happen
and the Ranger will power OFF again about 30 seconds
after the end of ringing.

4.1.3 The MON Setting (MONITOR Mode)

The MON position (MONITOR mode) causes the
Ranger to enable its amplifiers so that you can listen
to a line without loading it. On-hook Caller ID is also
received, checked and displayed in this mode. In the
first minute of entry to MONITOR mode, if there is
no Caller ID or DTMF information on the screen, the
Ranger measures its battery voltage and estimates the
remaining battery capacity. On line 2, it displays the
time remaining to automatic power-off, the measured
line voltage, and the polarity. The Ranger also monitors
the line it is connected to for DTMF signals. If it detects
any of the 16 valid DTMF signals, it will display up to
32 characters, and keep them on the LCD regardless
of changes in the state of the monitored line.
