Operation and Specifications
Power-Up Check
To power-up the MS-2002, do the following:
> Plug in the MS-2002.
When power is first applied to the MS-2002, it performs a power-up reset, in which the front panel indicators cycle
through all of their possible colors and then turn off. This verifies the general operation of the intercom station and
indicators. The MS-2002 also reads the settings of all DIP switches at this time and configures itself accordingly.
Test Tone
The MS-2002 can generate a test tone, which can be used to verify intercom channels operation after installation or to locate a
malfunction. This test tone is also used for the sidetone adjustment.
To use the test tone, do the following:
1. Simultaneously press the All Talk and PA keys to activate the test tone.
2. Tap the call key for the channel that you want to test (can be either a MS-2002 channel or an EMS-4001 channel).
3. Verify the test tone can be heard at all intercom stations on the channel.
4. Replace any defective cable or intercom stations where the test tone is being lost.
5. Tap the same call key to stop the test signal on that channel.
6. Press any key, except a Call key, to turn off the test tone.
