Dakota Digital 650360 manual Using Clock Offset, Troubleshooting guide

USING CLOCK OFFSET:

Because this auxiliary module displays the clock, it may be desired to disable the display of the clock on the main VHX screens. This makes it much more difficult to adjust the VHX clock because the main VHX system requires the clock screen to be displayed to set it.

To make clock adjustment more convenient in this situation, a clock offset may be set on this module. The steps are the same as setting the main VHX clock but it is done using the switch for this auxiliary module instead. It is important to note that the VHX time is not changed with this method. Instead a time offset from the main system time is set. If the main VHX clock display is enabled, this method will cause this time to be different than that displayed in the VHX system displays.

With the clock screen displayed, press and hold the switch. The hour will begin to flash.

Press and release the switch to adjust the hours.

Press and hold the switch to move to tens of minutes. Tens of minutes will begin flashing.

Press and release the switch to adjust the tens of minutes.

Press and hold the switch to move to the single minutes. Single minutes will begin flashing.

Press and release the switch to adjust the single minutes.

Press and hold the switch to apply the offset and return to normal display.

NOTE: If the VHX system clock time or the BIM-16 clock time is adjusted, the auxiliary module clock offset will automatically be reset to zero so the time displays are resynchronized.

If the screen selected is a reading from a BIM module, check that the BIM module is connected and functioning properly.

If the channel of the BIM has been changed, turn the key off and then back on so the VHX system can search for the correct channel. Also verify that the new channel isn’t already used by another BIM unit.

Turn the key off then back on to allow the VHX system to relearn the new BIM channel locations.
