Electrical Checks

1. Plug the ACU into the AC Power and make sure that the AC light comes on. If the ACU needs

charging the charge light should come on. Leave the ACU plugged into AC until the charge light

goes out. This should also be done to all ACUs that are stored for longer than one month. The

battery inside the ACU can be damaged by leaving it in a discharged state.

2. The front display should display the ACU and iTX serial number. The display will then show the

current date and time. If any of these numbers are incorrect, change them to the right values by

using Extended Function Mode (as described on Page 29).

3. Using Function Mode on an ACU, enter Test Mode and check the AC and Telephone Disconnect

by unplugging the cables from their respective outlets (For more Information concerning Test

Mode consult Page 31).

4. The stored events should be erased each time the ACU is changed from one participant to

another. Be careful because once the events have been erased they can never be retrieved. To

erase the events, enter Function Mode and step through the functions until “B=Clear Events”

appears. Push ‘B’ button once. The display will then prompt “A=** Clear **” Press ‘A’ to erase the

events. Once the events have been erased "Events Cleared" will be displayed.

5. If the ACU was used as a passive unit or previously had its phone number changed, check the

phone number. Use Extended Function Mode to change the phone number back to the original

number. (For More Information on accessing Extended Function Mode see Page 26.)
