Installing Batteries

The transmitters and the receiver are each powered by two AA batteries. To install batteries, please follow these steps:

1. Turn OFF the units. Slide the battery-compartment catches inward (in the direction of the arrows "→ ←").
2. Take out the battery holder.

Diagram shows the battery compartment being opened and the battery holder being removed.

Insert the batteries into the battery compartment by matching their polarities to the indications inside the compartment. Then, set the battery holder in the original position.

Diagram shows batteries being inserted into the holder and the holder being placed back into the compartment.

Battery indication: The battery condition is shown by the BATT indication in the display section.

Note: The indicated battery condition may not be correct if the batteries were not new when installed. If you plan to use the component for a long period, it is recommended that you replace the batteries with brand new ones.

Notes on battery:

• Batteries may leak or explode if mistreated. Be sure to follow these instructions:
• Make sure to install the batteries with correct polarity.
• Always replace two batteries together.
• Do not use different types of batteries or old and new ones together.
• When not using the components for a long period of time, remove the batteries to avoid leakage. If the batteries do leak, clean all leakage from the battery compartment and the component.

CAUTION: Danger of explosion if battery is incorrectly replaced. Replace only with the same or equivalent type recommended by the manufacturer.

When you dispose of the battery, you must obey the law in the relative area or country.

To attach the belt clip:

Insert a pointed object such as a ballpoint pen between the belt clip and the transmitter to make some space between them, and then remove the end of the belt clip from the hole on the side of the transmitter.

Diagram shows a tool being used to release the belt clip from the transmitter.

Reorienting the belt clip:

The BY-WM8's belt clip can easily be removed and reattached to the body pack, so you can mount it upside down. To reorient the belt clip, please follow the below steps:

1. Push outward on the belt clip at one of the hinges, so one side of the clip is detached from the body pack.
2. Push the belt clip out from the other hinge to completely remove the clip from the body pack.
3. Realign the belt clip with the body pack, making sure the clip is facing the desired direction.
4. Insert the two-way belt clip into the body pack, one hinge at a time.

Diagrams show the steps for removing, reorienting, and reattaching the belt clip.
