General Information

The GAI-Tronics Model 295F Flush-Mount and Model 295W Wall-Mount Clean Phone™ Telephones
are designed for the exacting requirements of clean rooms. They are constructed of stainless steel and
have a completely smooth polyester front panel that will not trap particulate matter. Calls are made by
pressing one of the two auto-dial buttons or by using the fully functional keypad. The Flash button
allows the phone to use the features of a PBX system. The oversized, clearly labeled buttons allow for
easy operation with gloved hands.
Auto-Dial Buttons
The Model 295 Clean Phones feature two auto-dial buttons to store frequently dialed telephone numbers.
If using the auto-dial feature, it is important to program the Auto-dial Time Delay option, which sets the
amount of time lapse between the auto-dial button press and the actual dialing operation. The default
time period of ten seconds could be too long if the feature is to be used for emergency communication.
This feature is fully explained in the Programming Information section.
Auto-Answer
The Model 295 also offers a programmable activation/deactivation of the Auto-answer feature. When
activated, this feature determines how many rings must elapse before auto-answering. The Auto-answer
feature allows the telephone to go off-hook automatically so technicians do not have to leave their work
stations to answer the telephone.
A light under the ON portion of the ON/OFF button is activated to indicate if the telephone is off-hook.
If the Auto-answer feature is not activated, the telephone will not go off hook until someone actually
touches the ON/OFF button.
