Switch 2 - Station Edit Lockout

When switch 2 is set to "ON" access to the Station Edit Mode will be restricted. Therefore there can be no tampering

of the Station (Event) times.

Switch 3 - Time Edit Lockout

When switch 3 is set to the "ON" access to the Time Edit Mode will be restricted. Therefore there can be no changes

made to the current time.

Switch 4 - Clear Memory Lockout

When switch 4 is set to the "ON" access to the Clear Memory Mode will be restricted. Therefore there can be no

erasing of the Station (Event) times stored in memory.

5.0 BATTERY BACKUP

Inside the unit is the battery used to backup the internal clock chip. If DIP switch 1 is set to "ON" and the unit fails to keep

the correct time after a power failure then it may be possible that the backup battery is flat. To replace the battery, remove

the lid and use a CR2032 battery (such as Altronics S 4999A) as the replacement. The location of the battery is shown in

Fig 5.1.

6.0 REAR CONNECTIONS

6.1 24V DC Connectors

DC sockets have been provided for 24V DC input and a 24V DC output. These two sockets are connected in parallel inside

the unit, so either could be used as an input or output or both as inputs. Two sockets have been provided so that the

power can be daisy chained to another device. The Altronics P 6717 DC power lead has been designed for this purpose.

The sockets also have a threaded connector so that the Altronics P 0602 2.1mm DC Plug with collar can be screwed onto

the DC socket so that the DC power lead cannot be accidentally pulled out.
