Do not leave the unit or the battery in a car. CAUTION When you replace the battery, be sure to first turn the power off to the unit. Otherwise, malfunction or damage to the data may occur. NOTE • You can use an AAA rechargeable battery (NiMH battery) instead. NiMH battery life is estimated to be about 70% of that of an alkaline battery. Also, NiMH battery power voltage is different from that of an alkaline battery. Therefore, the remaining battery power may not be displayed correctly. Please note that you cannot recharge an NiMH battery using the PR7. • The microSD card slot supports both microSD and microSDHC card formats. If you plan to use a microSD card, choose a 1GB-2GB microSD card, or a 4GB-32GB microSDHC card (these cards are compatible as of January 2013). However, some cards (depending on the manufacturer or type of card) may not work with the unit. • For more information about microSD cards, please visit the following Yamaha Pro Audio website: http://www.yamahaproaudio.com/pr7/ Preparing the PR7 Turning the power on or off Turning the power on Press the [■] (Stop) button.
