individuals can use their fingernail to pull it open.

Hearing instruments can be turned on once you have placed them on your ears. If you prefer to
turn them on just prior to placing them on your ear, your hearing care professional can activate a
function called SmartStart.
This function will delay the time in which the hearing instruments turn on by ten seconds after
the battery compartment is closed. This reduces the risk that the hearing instruments will whistle
while you put them on. With SmartStart, a beep will be heard for each second of the delay period.
