Switches
A slider control, located below the dial pad, between columns DI/EI and FI,
controls the handset and headset receive volume level. See Figures 1 and 2.
A Power Fail Transfer (PFT) switch is located in the baseplate. See Figure 3
on page 21. Both the line connector and the RS-232 connector for the PC port
are located at the back of the console.
Shift key
The Shift key, mentioned earlier, is positioned in column FK, row 1, just
above the Hold key. See Figures 1 and 2. It is used to access Level 1 mode
functions.
Handset and headset jacks
Two pairs of jacks are provided for plugging in handsets or headsets. The
jacks are located on both sides of the console beneath the faceplate in the
recessed area shown by the arrows. See Figures 1 and 2. The console accepts
both carbon and electret handsets or headsets and automatically adapts itself
to each type.
Note: Electret headsets and handsets are polarity sensitive and must be
correctly inserted into the jack.
LCD indicators
The LCD indicators on the M1250 and M2250 display triangular symbols that
normally point towards the key with which they are associated. Certain keys
in the QMT2 mode of operation and loop keys have two LCDs associated
with each key instead of one.
On the M2250, every LCD can flash at 30, 60, or 120 impulses per minute
(ipm). On the M1250 console, certain lamps can flash only at 60 or 120 ipm.
Refer to “Attendant console operation” on page 29for more details.
The M2250 attendant console has 10 more flexible features than the M1250
attendant console. These are programmed in LD12 and accessed using the
Shift key.
