The reset button on the AR-DL10 is the 'ACL' button. On my unit it is just above the Start/Stop button. On some of them it is in the battery compartment.

Turn off the remote, hold down the temp raise button until you see the F or C appear, hit the temp raise button again to select F or C, turn on the remote.

In many units no option to use manually without remote and also it's not advisable. With your statement, I conclude your remote is defective and not repairable. Replace with new remote. Helpful?

Right above the 'CLOCK ADJUST' there is a small hole, you need to push a ballpoint pen or something into that hole, to allow you to set the clock using the - and + buttons next to it. Then press the pen into that hole again in order to finalize the time.

If your remote control have display but cannot transmit signal to the unit. Confirm first if the remote is really the problem, using your camera or cellphone camera as your eyes point the remote transmitter to your camera and "on" the remote. You should see light emits in your remote control, if no emitted light then the remote control is defective. But if there is a light the defect is in the unit receiver.

Check also if there is a reset or rst button in your remote control and reset it and try.

Check also if there are error codes in the unit, reset the unit by disconnecting the power supply in the unit for 10 sec. and "on" again and try.

The unit can be operate without remote control, use the manual button located in the unit.

If the remote control have no display replacement of remote is recommended.
