Depending on which frequency your instrument operates on, your instrument might be equipped with the functionality to include internal batteries. Please find below a guide on how to open and change batteries.

Opening the instrument

To open the instrument, hold the housing in one hand and unscrew the end bell nut by turning it counterclockwise (Step 1)

Remove the end bell (Step 2), by gently pushing or pulling it straight out of the housing (Do not twist).

Pull out the battery cradle from the housing (Step 3).

Changing the batteries

The Aquadopp 2 can accommodate up to either three alkaline 50Wh, three lithium 165Wh or three rechargeable lithium-ion 75Wh batteries.

Do not mix alkaline and lithium batteries!

Start by connecting the battery harness (female) to the 2-pin connectors (male) that are attached to the battery cradle (Step 4). Then, place the new battery into the cradle (Step 5). Finally, tightly secure the battery in place using the attached strap (Step 6). Repeat for up to three batteries.

Closing the instrument

Place the battery cradle back into the housing (Step 7) ensuring that the cradle connector mates with the head connector (Step 8).

The battery cradle only fits one way, and the correct mating is indicated by a visible ring (1 cm) of aluminum (Step 9 & 10).

Gently insert the end bell until it mates with the housing (Step 11).

Gently screw the end bell nut on to the housing by turning it clockwise (Step 12 & 13).
