Atek electronic LG10B User Manual

If later in the same session you want to increase the number of auto-off minutes, 
when you push and hold 

 and push 

 the screen will display the next one 

minute increment above what you have already added.
For example, if your normal auto-off time is set to one minute, and for this session 
you added one minute for a total of two minutes, and later if you want to add two 
more minutes to increase the total auto-off time to four minutes (one set minute 
and three additional minutes added for this session), first the screen will display 2 
(because you already added one minute and now you are adding a second additional 
minute) and then when you push 

 again the screen will display 3.

So, the screen always displays the accumulated number of minutes that have been 
temporarily added to the normal auto-off time any time during this session. Note that 
it just displays the added time, not the normal (set) auto-off time. Total auto-off time 
for a session is the normal (set) auto-off time plus any additional minutes you have 
added temporarily for the current session. 
Your Logio allows a maximum total auto-off time of ten minutes. So, if your normal 
auto-off time is set to one minute, you can temporarily add up to nine more minutes 
for a session. If your normal auto-off time is set to two minutes, you can temporarily 
add a maximum of eight more minutes, and if your normal auto-off time is set to 
three minutes, you can temporarily add a maximum of seven more minutes. You can 
add more minutes at any time during a session as long as you have not yet exceeded 
the maximum ten minutes allowed.
Once you add auto-off time for a particular session, the only way you can reduce the 
time without turning off your Logio is by pushing the 

 button and viewing (but not 

necessarily changing) the auto-off time setting – when you do that, the temporarily 
added time is cancelled. 
As soon as you manually turn off your Logio, or it turns off automatically, the session 
is over and there is no longer any temporarily added auto-off time next time you turn 
it on since the added time only applies to the current session and is not a setting 
change.
