Your Whistler unit is expertly engineered and designed to exacting quality standards to
provide you with reliable, trouble-free operation. If your unit has been correctly installed
following the guidelines in this manual, but is not operating optimally, please refer to the
troubleshooting guide below.
Problem: Unit will not turn on.
•Check the proper installation of the batteries.
•Press and hold the Power/Menu/ESC button for 3 seconds
Problem: Clock doesn’t work or displays the wrong time.
•Position yourself in a clear area so the unit can obtain a satellite signal. Once a satellite
lock is established the clock will display the time. Unit will not automatically adjust the time.
Go into the setting menu and select your time zone to have the unit properly display the
correct time. Also check the “Time DST” setting if the clock is still incorrect. See page 17.
Problem: Why are the distances shown incorrect for each hole?
•Check the unit’s setting in the set up menu to be sure the distance units (yard or meter)
are correct.
