Charging the MXA-HST
The MXA-HST comes with a built-in rechargeable battery. Prior to using the handset
for the first time, fully charging the battery is highly recommended.
To charge your handset:
1. If you wish to charge your MXA-HST via USB, insert the USB plug of the
Charging Cradle (FIG. 2) into an available USB port on the Modero X Series
touch panel.
2. Insert the base of the handset into the Charging Cradle. The indicator light on
the back of the handset will turn blue while the handset is charging and solid
white when it is fully charged. The charging indicator will be delayed for a few
seconds if the handset has not been used for a long time or the battery is
drained.
NOTE: Use only the supplied Charging Cradle and USB charging cable to
charge the handset.
WARNING: Do not use the handset while it is seated in the Charging Cradle.
NOTE: Fully charging the handset may require up to three hours.

2. To activate the pairing mode, press and hold the handset’s Multi-Function
Button (MFB)(FIG. 1) for 8 seconds.
3. From the touch panel’s Settings Pages, pair the device with the touch panel. For
more information on pairing a Modero X Series touch panel with a Bluetooth
device, please refer to the Modero X Series Programming Guide, available from
www.amx.com.
4. If the pairing cannot be completed within three minutes after the pairing mode
has been activated, the indicator light on the back of the MXA-HST will flash red
rapidly five times and then shut off. Repeat steps 1 through 3 to pair both
devices again.
Resetting the MXA-HST/Removing Its Pairing History
