Installing the Antenna, Operating the XM Tuner

Commercial Audio Series Business Music System

3 Operation

INSTALLING THE ANTENNA

1. Connect the antenna.

Connect the included XM antenna to the XM antenna input on the back of the 180MAx.

You will be mounting the antenna near a south-facing wall. The antenna comes with 20 feet of cable. If that is not sufﬁcient to reach the 180MAx, purchase a 50-foot cable extension kit. Up to two extensions can be used together for up to 120 total feet of cable. Alternatively, you can use custom lengths of 50 ohm RG58U, or obtain extension kits from third-party sources. For outdoor antenna installation options, go to www.xmradio.com

2.Turn on the 180MAx.

Verify the power indicator is illuminated and the display backlight is on.

If the message “CHECK ANTENNA” appears, check that the antenna connector is tightly connected and that the antenna cable is not shorted.

3. Align the antenna.

For indoor installation on a ﬂat surface:

Set the antenna on its base on a ﬂat horizontal surface, ideally near a south-facing wall, and near a window if possible.

Turn the base of the antenna so that the XM logo is facing to the south if you are in the eastern half of the U.S. and to the south/southeast if you are in the western half of the U.S.

For outdoor installation:

See www.xmradio.com for third-party outdoor installation options.

For indoor wall mounting:

You will mount the antenna near a south-facing wall, and near a window if possible.

1.Insert four screws (not supplied) in the wall so they align with the holes in the base of the antenna.

2.Tilt the antenna fully back on the base.

3.Place the antenna base on the four screw heads with the antenna pivot at the top.

4.Pull down the base approximately 1/4 inch until the base is ﬁrmly secured. The XM logo will be upside down when the antenna is properly installed.

4. Optimize the signal strength.

Have someone hold the antenna as you optimize the signal strength (described next).

A display will appear similar to the one below:

Direct

Signal-strength indicator

At the bottom right of the screen is a small box that indicates signal strength. Orient the antenna to achieve maximum signal strength (ﬁll the box as much as possible).

If the antenna does not have a clear path to the satellites, the display will read “NO SIGNAL”.

5. Set the listening volume.

Turn up the XM input volume control until you hear the XM radio signal at a low volume. If the system is working, you will hear XM programming on channel 1 and you can proceed to activate the 180MAx.

6. Activate your XM account.

After verifying channel 1 audio, you must activate your XM account to access all XM channels. Commercial accounts must sign up for and activate under the terms of XM’s Commercial Service.

First obtain the XM Radio ID number of your unit. Turn the Scroll knob until you see channel 0 on the LCD display and press the Scroll knob to select this channel, or press Direct Entry then 0 and OK on the remote control. The 8-digit XM Radio ID will appear in the top section of the display.

Record the 8-character ID in the space below, noting that letters I, O, S and F are not used and that the number zero has a line running diagonally through it.

XM Radio ID: _________________________

Activate your XM radio service by calling XM at 1-800-XM RADIO (1-800-967-2346). Commercial accounts cannot be activated via the Internet. A listener care representative will help you activate your unit. Customers should have their Radio ID ready; the Radio ID can be found by selecting channel 0 on the tuner with the Scroll Knob to the right of the LCD Display.
