Switching on and off
Your hearing instrument is switched off by opening the battery
door.
Switch your instrument on by closing the battery door.
Your instrument may have a programme button to switch pro-
grammes. How ever, if you close the battery door your instru-
ment will always start in programme number 1. Read more on this subject on
page 21.
At night, leave the battery door open. It increases battery life and allows mois-
ture in your instrument to evaporate and increases the instrument’s life span.
Delayed Activation
Your hearing care professional may have activated the Delayed Activation function in your hearing instru-
ment. This function will delay the time in which the hearing instruments turn on by several seconds after the
battery compartment is closed. With Delayed Activation, a beep will be heard for each second of the delay
period. If you wish, this function can be deactivated by your hearing care professional.

(Please ask your hearing care professional what battery size is used for your hearing
instrument )
Low battery indication
Your hearing care professional can set your hearing instrument to give an acousti-
cal indication when the battery is reaching its end of life. The hearing instrument will
reduce amplification and emit a melody if battery power gets too low. This signal will
recur every fifteen minutes until the hearing instrument automatically switches off. It
is recommended that you keep spare batteries on hand.
Replacing the battery
Open the battery door by placing your fingernail or a pencil under the edge of the
battery door and gently push it backwards. When opened, remove the dead bat-
tery. The end of the cleaning brush is magnetic. It allows for easy battery removal/
insertion.
i
Always use new Zinc-Air batteries that have a minimum remaining shelf-life of
1 year.
Remove the protective foil and wait 2 minutes to allow full activation of the battery
before inserting the battery (plus side facing up) into the hearing instrument. You will
recognize the plus side of the battery because it is marked with a +. Check whether the + symbols on the
battery and on the battery door are on the same side.
