3. PROGRAMMING THE COX 4050
Entering The Programming Mode
Press the right arrow key until Secondary is displayed. Press the alter key and.’CODE ****’ will be displayed. A
four-digit code can now be entered (serial number). On each press of a key the ‘*’ will change to ‘+’ in
sequence from left to right. When all four ‘*’ have been set the code is automatically checked. If the display
shows ‘WRONG CODE’ then try again making sure that you are entering the correct code, as each instrument
has a different code setting. If a mistake is made during setting, then use the CLEAR key and try again.
If you are sure that the code is correct and the instrument still shows WRONG CODE then it is probable that
the batteries need changing in the hand held remote control.
If you press the ALTER key by mistake the display will revert to normal after approx. 20 seconds. Pressing the
Е Ж keys will have the same effect. Pressing any other key will reset the timer allowing sufficient time to enter
each digit of code.
Exit program mode by pressing clear.
The Code Number
The code number for each instrument is taken from the last 4 digits of the serial number. The serial number can
be found on the front page of this manual, on the rear of the instrument, and is also displayed when the
instrument is first powered up, and finally by entering the Front panel Test routine.
For complete security it is recommended that the remote controller should be kept in a safe and secure place.
Unable To Enter A Code?
1) Enabling and disabling the Infrared hand held keypad.
The infra-red keypad will work with any COX unit and therefore it may be necessary to disable this function on
one unit where they are in close proximity. To LOCK OUT the infrared keyboard you must enter the Front Panel
Test Routine and select N for the ENABLE IR control. Once locked out, the infrared keypad is totally inactive on
that particular unit and the lock LED will be lit in the lower square panel. With the REMOTE OFF the displays
may still be viewed by means of the front panel keys. To restore operation of the infra-red keyboard use the
Front Panel Test Routine and select Y to the ENABLE IR menu.
2) Automatic LOCK OUT
In some cases the instrument itself will inhibit the ALTER key as it may be performing a sequence of events
that can not be interrupted, i.e. BATCHING. Please see the special instructions if applicable.
Unable To Use The Keys Or Key Bounce
If you are experiencing key bounce or you are unable to use the keys then there is probably interference with
the infra-red remote control. Problems may occur when trying to operate the unit in direct sunlight; or using
sodium lights etc. If there are problems then please contact your supplier.
