be controlled by the optional GRC 10 Wireless Remote Controller. An GRT 10 Wireless Transceiver
must be installed and connected to the GDL 69A, and the GRC 10 wireless remote must be configured
to recognize the installed GRT 10 transceiver for the GRC 10 wireless remote to function.
To validate the operation of the GDL 69/69A, monitor the multi-function display weather depiction page
and look for display of weather data. Depiction of weather data should begin within 10 minutes.
To validate the operation of the optional GRT 10/GRC 10 Remote System, use the GRC 10 to change
XM Radio channel or volume and monitor the GRC 10 display or audio from the audio panel.
2.4 Servicing Information
GRC 10 Remote Control Battery Replacement
If the unit does not turn on, or the battery level indicator on the display shows no bars, replace the
batteries. To replace the batteries in the GRC 10 Remote Control, remove the back cover of the remote.
Insert fresh batteries with the orientation as shown in the diagram in the battery compartment. Both
batteries should be replaced with fresh batteries at the same time.
Do not use lithium batteries in the GRC 10.
When replacing batteries, use only new or fully charged batteries. Do not mix new and
old batteries as this can cause battery leakage and damage to the unit. Do not mix battery
types (i.e. rechargeable with non-rechargeable).
Remove batteries if the GRC 10 will not be in use for several months. Storing batteries
in the unit for prolonged periods may result in leakage and damage to the battery
compartment.
Remove batteries when the GRC 10 is stored for extended periods.
