Important: Do not leave the collar on your dog for more than 12 hours per day to prevent pressure necrosis (bed sores).

4.3 modos de entrenamiento
The GROOVYPETS T221 offers three primary training modes:
- Modo de tono: Delivers an audible beep. This is often used as a warning or positive reinforcement.
- Modo de vibración: Provides a non-harmful vibration. There are 8 adjustable levels of vibration intensity.
- Modo de estimulación estática: Delivers a humane static pulse. There are 16 adjustable levels of static intensity. Always start at the lowest level and increase gradually to find the appropriate level for your dog.
To activate a mode, simply press the corresponding button on the remote transmitter.
4.4 Automatic Anti-Bark Mode
The collar can be switched into an automatic anti-bark mode to help control excessive barking. This mode progressively increases stimulation levels from 1 to 6 if barking continues.
- To Turn On Anti-Bark Mode: Ensure the receiver is in dog trainer mode. Press the sound (tone) and vibration buttons of the transmitter simultaneously for 3 seconds. After successful activation, a beep sound will be emitted, and the green light on the receiver will flash.
- To Turn Off Anti-Bark Mode: Press the sound (tone) and vibration buttons of the transmitter simultaneously for 3 seconds. The receiver will emit two beeps, and the green light will flash twice after successful shutdown.
Consejos: When anti-barking mode is active, the remote training functions (tone, vibration, static) can still be used normally. The receiver will respond to both remote commands and automatic bark detection.

4.5 Foolproof Safety-Lock Feature
