Kustom Signals Golden Eagle II Operator's Manual page 48

The Golden Eagle II will automatically run an internal test
prior to locking any speed. Depressing the TEST switch
will allow the Golden Eagle II to complete a display and
internal test then return the locked speed.
7. To manually unlock or clear the locked speed, depress
the LOCK/REL switch. This will clear the LOCK
window.
8. If the operator changes the mode of operation, such as
stationary to moving, the locked speed will be
automatically unlocked and cannot be recalled.
9. If the remote control is damaged or lost, refer to Section
4.2.0 for default operation of the Golden Eagle II
without a remote control.
7.2.0. Fastest Vehicle--Stationary Operation
1. The Golden Eagle II allows two methods of fastest
vehicle mode (Push and Hold control or Toggle
control). See Sec. 13 (Options) for selecting the
preferred method.
2. When a fastest vehicle is detected the FASTEST LED
will flash and the LOCK window will display the speed
of the fastest vehicle detected by the Golden Eagle II.
(The TARGET window will continue to display the
speed of the strongest target vehicle.)
NOTE: This is especially useful in traffic situations
such as a small vehicle overtaking a larger truck.
In the FASTEST mode, as in normal radar
operation, a good tracking history is essential.
3. The operator may lock the fastest speed by depressing
the LOCK switch while a fastest speed is displayed.
The strongest speed may be locked by depressing the
LOCK switch when only the strongest speed (no fastest
speed) is being displayed.
