Regular cleaning helps keep your e-collar functioning properly and prevents irritation on your dog’s skin. The PE-900 system is waterproof, but it should still be cleaned carefully to maintain the electronics and contact points.

Step-by-Step Cleaning Process

1. Turn Off the System
Before cleaning, power off both the transmitter and receiver to avoid accidental stimulation.

2. Remove the Collar Strap
Slide the Biothane strap out of the receiver if possible. This allows you to clean both the strap and receiver more thoroughly.

3. Wipe the Receiver and Transmitter
Use a soft damp cloth to wipe dirt, mud, or saliva from the receiver and handheld transmitter. Avoid soaking the units or submerging them in water.

4. Clean the Contact Points
Dirt and oils can build up around the metal contact points.

• Use a soft brush or cloth to remove debris.
• If needed, lightly dampen the cloth with water to wipe them clean.
• Ensure the contact points are dry before placing the collar back on your dog.
  

5. Clean the Collar Strap
The Biothane strap can be cleaned separately with mild soap and warm water. Rinse and allow it to fully dry before reattaching.

6. Inspect the Equipment
While cleaning, check for:

• Loose contact points
• Dirt in the charging port
• Cracks or wear on the strap
• Corrosion on metal parts
  

7. Dry Completely Before Use
Make sure all components are fully dry before charging or using the collar again.

The E‑Collar Technologies PE-900 Pro Educator uses a magnetic on/off system to power the receiver collar and a standard power button for the handheld remote.

Turning On the Collar (Receiver)

1. Locate the Red Dot
   
   On the receiver unit, you’ll see a small red dot. This is the magnetic activation point.
   
2. Use the Remote to Activate It
   
   On the back of the remote transmitter there is a magnetic on/off switch.
   
   Place the back of the remote against the red dot on the collar.
   
3. Watch for the Indicator Light
   
   The receiver will flash green and you’ll hear a short beep indicating the collar has powered on.
   
4. Remove the Remote
   
   Once the light flashes, the collar is on and ready to use.
