conditioners, and heater ducts since they may cause interference and reduce
the module's sensitivity
• Select a site that is not susceptible to drastic temperature changes
• Mount the MG-RCV3 as central as possible to the proposed placement of the
transmitters
• Mount the MG-RCV3 as high as possible
• Avoid mounting the MG-RCV3 in the basement as the range of the module is
reduced when mounted below ground level. However, if it is absolutely
necessary to mount the module in the basement, mount the module as high
and as close to the underside of the first floor as possible
• Mount the MG-RCV3 on a wall allowing at least 5cm (2in) around the module
to permit adequate ventilation and heat dissipation
Refer to the appropriate Programming Guide for maximum allowable
distances between the control panel and the MG-RCV3.

2.2 Noise Level Test

The MG-RCV3 performs a test on power-up that verifies the noise level in the
surrounding environment. If the environment is too noisy, the module's RX LED
will illuminate (refer to Figure 2.2 on page 6) and will remain illuminated until
the module is powered up again. In such cases, power down the Magellan
module, change its location, and then power up. Repeat this procedure until
the module's RX LED no longer illuminates. If all possible mounting locations
have been tested and the environment is still too noisy, be aware that the
wireless system may not function properly. The noise level test should be
performed in conjunction with the signal strength test (refer to section 5.2 on
page 12) to ensure optimal mounting locations for the MG-RCV3 and
transmitters.
When performing the noise level test, ensure that there are no
transmitters that are powered-up.

2.3 Connections and Mounting

1. Using a screwdriver, remove the screw on the MG-RCV3's front
cover and then remove the front cover.
