3.1.4 Clearing the Memory

This function will clear the internal memory, erasing any information entered.

The memory must be cleared before using the unit for the first time.

Navigate to the "Clear Memory of ON/OFF times" Sub Menu as shown in Fig 3.3.

Press "Enter" to activate this option. If DIP switch 4 is set to "ON" the screen will display the message shown in Fig 3.15.

This is one of the security options to protect the information stored in memory. See the DIP Switch settings for more

information. Set the DIP switch 4 to "OFF" and then press "Enter" again. This time you should enter the Clearing the

Memory Sub Menu. The following two screens should be briefly displayed.

This will clear

all ON/OFF times

Then you will be asked to press "Enter" to confirm you want to clear the memory or press "Menu" to exit.

If you press Menu you will return to the Clear Memory Sub Menu.

If you press Enter, the unit will cycle through the memory locations clearing any data stored. This will take a few minutes.

Once finished you will return back to the Clear Memory Sub Menu.

NOTE: It is advisable to now set DIP switch 4 to "ON" to prevent accidental clearing of the memory.-

4.0 DIP SWITCH SETTINGS

There are four DIP switches accessible on the rear of the A 1707A which are for selecting the backup battery and various

security lockout features (See Fig 4.1).

Switch 1 - Battery Backup

When switch 1 is set to the "ON" position the internal battery is connected to the units clock chip. If power is

ever

removed the battery will ensure the clock chip continues to run and therefore keep the current time.

NOTE : This battery does not provide backup power to the entire A 1707A unit. The display will not light up and

the unit will not function. Only the internal clock chip will still be supplied power.

If the entire A 1707A requires backup power a backup power supply can be connected to the 24V DC input.
