1. Volume Adjust
Door station can adjust its talking volume by keypad. Note
that the volume adjusting function is automatically activated
in the Debug Mode.
After Volume-Adjust is activated, if Door Station calls a Moni-
tor and enters talking state, current volume values are shown
on bottom line.
The left value means the microphone volume of door station,
and the right value means the speaker volume of the door
station. Each value can be adjusted separately, ranges for 01
to 25, and 15 by default.
2. Auto –Dial back
The Auto-Dial-Back option is designed to simplify field debugging, and to realize single person
testing. Also, it is always used to get a Monitor’s Room Code.
After Auto-Dial-Back is activated, by pressing Monitor’s Call Button, the Monitor’s Room Code is
shown at the Debug Message Area of screen. 3 seconds later, the Door Station will automatically
launch calling operation to the Monitor. However, if you don’t need calling, just press “*” when
Room Code is present. Please note: Auto-Dial-Back is automatically activated when you first enter
Debug Mode, and Switchboard doesn’t response to Monitor’s calling request in this condition.
3. Online monitor
Function: Search the certain range of Monitor which is for checking the information of the online
monitor. After startup this operation, the Door Station search and display the present online mon-
itor according to the setup range automatically.
4. Online Device
Door Station can search the devices on-line such as C5-MDS, C5-IPC, C5-IMC. The information will
be shown on the display after the searching.
Note:
- For installations using hand free Monitors, it’s important that volume values in both
directions must be adjusted correctly. Otherwise, conversation maybe hard to hear, or
discontinuously, or feedback.
- The hand free conversation quality between Monitor and Door Station is related to
distance between them. On the back of hand free Monitor, a yellow rheostat (Variable
Resistor) serves as adjuster, to adapt to distance.
