Whenever the function Fn 39 is enabled, the WAKE-UP ALARM will be automatically deactivated until Fn 39 is disabled
again. However, the Wake-Up Alarm preset time will remain unchanged in the memory.
TO SILENCE the Wake-Up Alarm, press the MUTE key at any time while the alarm buzzer is sounding. The Buzzer will be
silenced and the Alarm deactivated.
In order to reactivate the alarm for the next day, press the SET key as described previously.
The Soft Wake-Up Alarm Buzzer feature controls the buzzer sound to come on less frequently at the beginning and becomes
more frequent as the alarm continues. This makes the wake-up alarm buzzer less annoying.
The Wake-Up Alarm Buzzer active period is limited to 4 minutes unless silenced or cancelled sooner.
UP/DOWN STOPWATCH TIMER and EVENT COUNTER
SELENA can be used to function as a presettable UP/DOWN STOPWATCH TIMER AND EVENT COUNTER with an Alarm
Buzzer and / or Internal Relay Control.
To enable the UP/DOWN STOPWATCH TIMER mode, make sure that the function Fn 39 is ENABLED.
For the Up/Down Event Counter mode, the function Fn 31 MUST also be enabled.
Possible timer/stopwatch formats:
A) In 4-digit display format ( Fn 9 disabled )
1. MINUTES : SECONDS format when function Fn 38 is enabled.
2. HOURS : MINUTES format when function Fn 38 is disabled.
3. SECONDS : 1/100 SEC format when function Fn 38 is enabled and Fn 35 enabled .
B) In 6-digit display format ( Fn 9 enabled )
1. HOURS : MINUTES : SECONDS format when function Fn 38 is disabled.
2. MINUTES : SECONDS : 1/100 SEC format when function Fn 38 is enabled and Fn 35 enabled .
NOTE that even in the 6-digit display models the 4-digit format may be selected ( Fn 9 disabled ) if necessary.
C) In models with TEXT display ( Fn 85 enabled )
Fn 72 HH-MM-SS-hh ( timer or counter ) ( also see Fn 35,36,38,39, )
Fn 73 Tmr MM-SS ( timer ) ( also see Fn 35,36,38,39, )
Fn 74 TIMER HH-MM ( timer or counter ) ( also see Fn 35,36,38,39, )
ATTENTION: In ALL TIMER MODES with 4-digit display and when the MINUTES:SECONDS display format (Fn 38) is
NOT SELECTED, the following will occur:
During the FIRST hour of the count UP or the LAST hour of the count DOWN, the display of Hours:Minutes will switch
automatically to Minutes:Seconds to allow the user to monitor the time with better accuracy.
NOTE, that the programming mode DOES NOT HAVE TO BE ACTIVATED to preset the Up/Down Timer/Counter, and it
may be performed at any time while in the regular clock operation.
To Preset the COUNT UP/DOWN STOPWATCH TIMER or EVENT COUNTER:
NOTE: If the function Fn 87 is NOT ENABLED, the Count-Down operation of the Timer is selected by presetting the
START TIME as different than 00:00(.00). Otherwise it will function as a Count-Up Timer. The Event counter can count
Up or Down independent of the preset but will not go DOWN past the 000000 count ( unless the function Fn28 for the
“looping” timer is enabled ).
1. Press the SET key to initiate UP/DOWN TIMER/COUNTER Preset Mode.
NOTE, that the display will automatically switch to the Timer/Counter Mode and will show the last preset.
2. Using the UP and DN keys, preset the Timer HOURS and MINUTES (or Counter Initial count) or leave it unchanged.
Use the NXT key to move from minutes to hours or seconds (or count digits) and back if necessary.
NOTE: To reset the time/count to 00:00 (:00) press the CLR key.
3. When finished, wait for several seconds without pressing any keys. The clock will resume the normal operation.
