Troubleshooting
If you think the monitor may be faulty, please check the following points before taking it to be repaired.  If afterwards it still does not work, contact the shop where you purchased the monitor or your nearest Sharp authorized Service Center.

The monitor's florescent tubes have a limited life span.
- If the screen darkens, persistently flickers or does not light up, it may be necessary to replace the florescent tube unit. Inquire at the shop where you purchased the monitor or your nearest Sharp authorized Service Center. (Never attempt this replacement on your own.)
- In the initial period of use, due to the characteristics of florescent tubes the screen may flicker. (This is not a malfunction.) If this happen, check by first turning off the power, then turning it on again.

How to set the Vodafone DTR remote to control your television

Find the brand of your television in the Set-up Code section and select the first 4 digit code in the list. Switch on your TV (not on standby).

Press the TV key and release it.

Press and hold down the Now’s Good key until the red LED underneath the TV key lights up twice.

Enter the 4-digit code for your television (the red LED should light up twice after having entered the fourth digit).

Press the Power key and see if you are able to switch off your television.

If your television does not respond, repeat steps with each code listed for your brand. If none of the codes listed for your brand operate your television, or if your brand is not listed, try the code search. 

Switch your television back on by pressing a number key (or CH+) and check if all the functions are working correctly.

Write down the code for your television on the inside of the battery cover  for quick easy reference.

Programming Notes

• If your device does not respond to the remote after trying all codes listed or your brand is not listed in the code list, use the Auto Code Search method to program your remote.
• Sometimes the first code that “works” with your device may operate only a few functions of your device. There may be another code in the code list that performs more functions. Try other codes from the code list for more functionality.

This is a trial and error procedure; and quiet time consuming. You might have to check different codes said for your device.

Code search

If your device does not respond to the DTR remote after having tried all the codes listed for your brand, you can try the Code search. During the Code search you will run through every available code in the DTR remote library. This method may also work if your brand is not listed at all.

Make sure that your television is switched on.

Press the TV key and release it.

Press and hold down the Now’s Good key until the red LED (underneath the TV key) lights up twice.

Press 9 9 1. The red LED will light up twice.

Aim the DTR remote at your device.

Next press power.

Aim the DTR remote at your Television.  Now press CH+ over and over, until your Television turns off.

Every time you press the CH+ key the DTR remote will send out a POWER signal from the next code contained in the PVR library.
You may have to press this key many times (up to 150 times) so please be patient. The Code search can take approximately 15 minutes.
If you skip past a code, you can go to the previous code(s) by pressing the CH- key. Remember to keep pointing the remote at your device during the Code search.

As soon as the device switches off, press Now’s Good key to store this code.

Press the corresponding device key when doing a Code search. If your device does not have a POWER key, press PLAY instead.

How to unlock a TV which displays a red key on the screen.

You will need the original remote to unlock the TV if you aren't sure of the unlock code. If you don't have the original remote, you will need to purchase one.

If you see a blank screen with a red key on the bottom of the screen, press 'Function' and 'Mute' at the same time. This should unlock the channel. This is an option for people who want the TV to stay locked but, want to be able to bypass the lock to watch a certain show or channel. All other channels will remain locked and the TV will fully lock when it is turned off.

Unlock all of the channels on the TV by entering the factory reset code. There are three main reset codes that TV manufacturers set. These are 0711, 6688 and 3308. Try each one until you find the one that works. This will reset the TV to original factory settings. When you do this, you will lose any information that you have stored in the TV, such as favorite channels, automatic timers and the clock. You will have to go through the full initial set up.
