NOTE: The MTX-3 can become unresponsive when battery strength is low.
Battery Calibration
For optimum performance after shipping or any time the unit’s power has been off
for an extended period of time, Crestron recommends the following procedure be
performed:
1. Place the unit on its docking station/charger and connect AC power.
2. Allow the unit to charge completely. (The green LED should be steady on
for 15 minutes.)
3. Remove panel from the docking station/charger.
4. From the main setup screen, touch Diagnostics, then touch Battery Diags
to go to the Battery Diagnostics screen. Touch Recondition Battery, then
touch YES, Recondition Battery to confirm. (Refer to “Configuring the
Touchpanel” which starts on page 13.)
5. Wait for the unit to shut off. This takes approximately five hours. Leave the
unit off the dock the entire time. During this operation, the Battery
Reconditioning screen shown on page 25 will be displayed until the unit
shuts off.
6. Place the unit back on the docking station and allow it to charge completely.
7. Unit is now ready for normal operation.

1. From the main setup screen, touch Standby Setup to enter the Standby
Timeouts screen (refer to “Standby Setup” on page 18). Use an Undocked
Standby setting of 30 and an Undocked Power Off setting of 45.
