4. If You Have Disabled Your Propaq LT Wireless (Radio)
Communications
1. If you have a model 802LTAN and have temporarily disabled its wireless communications (radio) and
intend to re-enable at some point, please re-enable before performing this update.
Note:
This does not refer to normal Acuity network disconnect through the Propaq LT user interface.
Disabling/enabling the radio is done separately using the 810-2775-xx PC Configuration Utility. It is
not possible to disable/enable the radio through the Propaq LT user interface.
2. To determine applicability, first check on the Propaq LT rear label that the model is 802LTAN.
(Models 802LT0N do not contain radios.) Then determine if the radio is disabled by:

Checking that there is not a communications icon in the top right area of the Propaq LT display.
If either of two communication icons are displayed ( ), the radio is not disabled.

Service>Radio> Show Info screen: Firmware version shows 'Version not found' and last screen
entry indicates "No radio card".
3. To enable the radio use the 810-2775-xx PC Configuration Utility. On the 'Feature Enable' tab in the
System Features group, check "Enable Wireless Communications" and send configuration to Propaq
LT.
4. After enabling the Propaq LT and running the Propaq LT v1.60.07 Update Application, if the update
application results in the “cannot update” message, you may choose to disable the radio and update
the Propaq LT. Caution: In this case however, if the radio is subsequently enabled the
Propaq LT will display a system fault and will be inoperable. Therefore, we recommend
NOT UPDATING the Propaq LT to v1.60.07 in this case and returning the Propaq LT to your
regional service center for update.
