Tac/Com Control Head Manual

SM06 Rev. 4.10

Anything visible on the screen may now be edited, SO BE CAREFUL!!! If channel numbers are being changed, be sure that they are CORRECT! A mistake here can be very difficult to correct later.

IMPORTANT!

This mode stays active until the unit is powered down, and is active for ALL RADIOS, not just the one initially selected. Anything that needs to be changed may be fixed, but be sure to power the unit OFF before normal operation.

If you are unsure of this function, PLEASE CALL NAT for more information!3.11.2 How Data is Stored in the Control Head

In current generation Tac/Com I and II controls, all detailed radio configuration data is stored in special software set-up routines, to make field changes much simpler.

The over-all operating software for the control head is stored in an EPROM (Erasable Programmable Read Only Memory), which is an integrated circuit storage device, and can be removed and updated through a service centre exchange.

These program updates come only from NAT itself. Some control head data, such as set-up information, channel labels and frequencies, are stored in EEPROM (Electrically Erasable Programmable Read-Only Memory) circuits and can be accessed and updated by the user/operator as required.

3.11. 3 Editing Considerations

It is important to remember that data stored in the EEPROM can be damaged by catastrophic component failure, severe static discharge (particularly by friction induced static during shipping if incorrectly packed), or accidental servicing or installation errors.

If odd or un-removable characters should appear in the display, particularly in unfortunate locations such as channel numbers, they can be removed via the 'MASTER EDIT' mode.

Channels should be set up in terms of easy scrolling access, with the most often used being close together in numerical sequence. This will save endless cycling back and forth, looking for channels.
