quick reference manual

1) SETTING DESIGNATED CHANNEL

Follow these steps to prepare different stations to different channels for use :

a) Set all units to the same CTCSS code (A/B/C or 1/2/3) at the back of the unit, for example, all units must be set on "B" (or "2").

b) If you need to assign your station to CHANNEL 3 (e.g. Kitchen). To turn on the intercom: rotate VOLUME clockwise until it clicks. The CHANNEL BUTTON 1 lights automatically (this is factory default channel). Sounds a BEEP tone. Set VOLUME to mid-range for comfortable listening.

c) Press and HOLD down (keep pressing) the CHANNEL button "3" for more than 5 seconds until you hear a BEEP tone sounds. WHEN YOU ARE STILL PRESSING THE BUTTON (WITHOUT RELEASING IT) AND THE CHANNEL BUTTON "3" LIGHTS.

d) That's it, now you successfully set up this unit as CHANNEL 3. This unit is designated station for your current location (e.g. Kitchen). You can release your press once this successfully done. Once the designated station has been set, write the corresponding name on the station label. Writes name (e.g. Kitchen) on position 3 of the Stations label. This will help you to remember whenever you want to call (e.g. Kitchen), press channel button 3, and call, then, talk.

If you need to set the other location (e.g. Garage) to CHANNEL 4. Follow the same steps as mentioned above to set up accordingly.

Writes different names on proper position of the Stations label for easy reference.

2) Location Troubleshooting Guide
This intercom operates on radio frequency (RF) signal.The signal strength has been optimized for effective operation within ordinary residential or small industrial complex. If reception problem is found; for example, no audio signal or poor reception, user can but separated within short distance (3 or 6 feet) to check if the problem persists.

The quality of RF signal is affected by interference and fading. Fading is the attenuation of RF signal and it is one of the reasons to cause poor reception. Fading can be caused by RF signal absorption due to reinforced concrete walls, metallic frames, heat exchangers or chicken wire fences encountered along the path of transmission. If the intercom units work perfectly in line-of-sight. Please check the placement of the units.

Jamming or interference is caused by the presence of another RF signal source, an intentional transmitter or unintentional RF signal leakage from faulty electrical appliances; for example, another transceiver operating on the same channel, a faulty transmitter or TV amplifier. Severe jamming can overload receiving circuits and cut off reception entirely. Move the intercom units to a new location (or use mobile phone battery with your unit and moving around to find good reception location) and test again.
