The Casio PQ40 uses AA batteries. To replace them, open the battery compartment at the back, remove the old batteries, and insert new ones, ensuring the correct polarity.
This may occur if the batteries are running low or are incorrectly installed. Replace the batteries and ensure they are properly seated. Also, check for any physical damage that may affect battery contact.
No, the Casio PQ40 only supports setting a single alarm at a time. You will need to adjust the alarm time manually if you need to set a different alarm.
To turn off the alarm, press any button on the clock. This will stop the alarm and reset it for the next day.
First, check if the batteries are installed correctly and have sufficient charge. If the problem persists, perform a reset by removing and reinserting the batteries.
