If the page line is in use immediately after hearing the two beep tones:
use the page signal to make
the offset level adjustment.
If the page line is inactive immediately following the beep tones:
a continuous tone activates to make
the offset level adjustment. Once the tone activates, the amplifier ignores all page line activity until
completion of the adjustment.
5.
Adjust the speaker volume potentiometer,
R91
, to the desired offset level.
N
OTE
:
Make this adjustment under maximum ambient noise level conditions. Always set the ALS offset
level higher than the ALS minimum level setting.
SmartSeries VLC Level
When activated, the VLC overrides the ALS minimum level setting allowing the speaker volume to
change to a preset level during an emergency page. To adjust the VLC Level:
1.
Remove the amplifier from the enclosure and place it on a stable surface.
2.
Connect the No. 10440-002 Maintenance Cable (
purchased separately
).
3.
Force the station into the VLC mode by executing a page from a station programmed by the MCU to
activate the VLC function.
4.
During the page, turn the speaker volume potentiometer,
R91
, fully counterclockwise (see Figure 14).
5.
Listen for two beep tones through the page speaker, indicating the amplifier is in the VLC adjustment
mode.
6.
After hearing the two beep tones, turn the speaker volume potentiometer,
R91
, to the desired speaker
level using the live paging signal to adjust the level.
The station automatically exits the VLC adjustment mode and reverts to normal operation five seconds
after the last potentiometer adjustment.
N
OTE
:
The system must have an ADVANCE head end to activate the VLC function.
FSK Signal Gain
The FSK signal gain potentiometer,
R13
, on the SmartSeries PCBA, adjusts the FSK transmit signal
strength. This setting is set at the factory. Do NOT adjust this setting.
Operation
After installing the ICS Page/Party plug-in amplifier in the appropriate 702, 703, 732 or 733 series
enclosure, Single party operation is as follows (multi-party operation in parentheses).
N
OTE
:
Use the Model 10401-201 Headset and 10416-103 Extension Cord (
purchased separately

1.
Lift the handset or connect a headset. (Select a free party line using the five-position rotary switch.)
2.
Press the handset pressbar or headset switch
3.
Page the desired individual (indicate the selected party line)
