Cleaning Your Console 

To test the display and lamps on a 302C console:

1. Press the 

POS BUSY

 and 

VOLUME UP

 button simultaneously.

2. When finished, press 

POS BUSY

 to place console back in service

To clean the console, use a slightly-dampened paper towel or soft cloth. Oily 
substances on the console may require considerable rubbing or the use of a mild 
cleaner, such as window cleaner or desk and office cleaner. If you use a cleaner, 
do not apply it directly to the console; instead, apply it to the cloth, then rub it 
onto the console.

Do not spill any type of liquid on the console. Liquids spilled on the console 
damage the electronic components.

If commercial power fails, the system’s battery backup keeps your console 
operating for a short time. When this short time expires, the power failure transfer 
automatically activates, and the console does not function. When power returns, 
consoles return to normal operation.

When power fails, all active calls and all calls on hold are lost. Also, a power 
failure affects the following features that require corrective action:

■

Attendant Control of Trunk Group Access — Reestablish control of 
desired outside lines.

■

Call Forwarding All Calls — Reactive Call Forwarding All Calls for 
desired extension numbers.

■

Controlled Restrictions — Reestablish control of desired phones or groups 
of phones.

■

Night Service — Reactivate Night Service as desired.
