OPERATION:

* POWER SWITCH ON MASTER MUST BE ON FOR SYSTEM TO BE OPERABLE.

1.When a station calls in, press the selector button corresponding to the lit LED. Station will continue to ring and station LED will remain illuminated until the call is answered at the master or reset at the sub.

2.To speak to the person at the remote station, press the TALK button on the master, and release TALK button to hear reply. If the master is equipped with a handset, communication can be with the handset or push-to- talk. Communication via the handset is VOX (voice actuated).

3.When the conversation is completed, press the OFF button to the left of the station button that is selected. Hang up handset.

CAUTION

*Do not connect any AC wires to any terminal on any unit, as damage may occur. Connect only specified power source to + and - terminals.

*Do not install more or different power sources than specified for the system.

*Do not attempt to install or connect wires on the NEM system while the system's power supply is plugged in.

*NEM masters and related equipment, unless specified as "weather resistant", are designed for indoor use only. Door stations (NE-DA, NE-JA, NE-SS, NE-SSR and NE-NVP) may be installed outdoors in a protected area. Do not expose any equipment directly to rain or extreme weather conditions.

IMPORTANT

*Any other manufacturer's products installed with the system (power supply, external device, etc.) are not covered under Aiphone's warranty.

*Do not mount NEM equipment in the following places, as it may cause the system to malfunction:

-High or extreme cold temperature areas: under direct sunlight, near equipment that varies in temperature, in front of air conditioner, inside a refrigerated area, etc.

-Places subject to moisture or humidity extremes.

-Places subject to environmental conditions, such as dust, oil, chemicals, salt, etc.

*NEM units are electronic devices, which must not be subjected to water or any other liquid.

*Severe weather conditions, such as lightning storms, may cause damage to NEM equipment. We recommend that power surge protection be installed to minimize potential component level damage.

-Install the SA-1 surge arrestor to protect the power supply from a surge.

-Additional SA-1 surge arrestors should be installed on all communication lines (one SA-1 for every two connected to master.).
