4.2 Pairing with Laser Level

The RC402 remote control is designed to automatically connect with compatible Spectra Precision GL412, GL422, GL512, and GL522 laser levels when both devices are powered on and within range. No manual pairing procedure is typically required for initial connection.

• Ensure your compatible laser level (GL412, GL422, GL512, or GL522) is powered on and operating correctly.
• Press the ON/OFF button on the RC402 remote control to power it on.
• The remote control display should activate and show connection status or default settings.
• If connection issues occur, ensure both devices have fresh batteries and are within the specified operating range. Refer to your laser level's manual for specific remote control communication details.

5. Operating Instructions

Once the RC402 is powered on and connected to your laser level, you can use it to control various functions remotely.

5.1 Powering On/Off

• To power on: Press the red ON/OFF button. The display will illuminate.
• To power off: Press and hold the red ON/OFF button for approximately 2 seconds until the display turns off.

5.2 Adjusting Grade and Slope

The primary function of the RC402 is to adjust the grade and slope of the laser beam remotely.

1. Ensure the laser level is set to a grade or slope mode that allows remote adjustment.
2. Use the Up (▲) and Down (▼) arrow buttons to adjust the primary grade (X-axis).
3. Use the Left (◀) and Right (▶) arrow buttons to adjust the secondary grade (Y-axis) or other directional settings, depending on the laser level's mode.
4. The LCD display on the RC402 will show the current grade/slope values as they are adjusted.

Consult your specific laser level's manual for detailed instructions on grade and slope modes and their interaction with the RC402.

5.3 Other Functions

The RC402 may offer additional functions depending on the connected laser level. These can include:

• Changing rotation speed.
• Activating/deactivating scan modes.
• Enabling/disabling mask modes.

Refer to the laser level's manual for specific button assignments and functions when used with the RC402.

6. Maintenance

6.1 Cleaning
