Spectra Precision RC402N Radio Remote Control
A new, full-function radio remote control is also introduced with these lasers. The RC402N comes as standard with the GL412N and GL422N grade lasers. It is included in several packages of the HV302 and is an option for the LL400HV. A new menu driven user interface has been added to the grade lasers as well as on the RC402N remote control that simplifies grade entry and access to advanced features which reduces learning time and eliminates complex button sequences. The displays are also backlit for ease of viewing when lighting conditions deteriorate. Using the radio remote allows contractors to operate the laser from up to 330 ft (100 m) away. The ability to make grade changes and start automatic alignments remotely can significantly reduce setup time and speed operation.

Spectra RC402N — Straight Answers.
Which lasers does the RC402N work with?
Spectra lists the LL300S, LL400HV, HV302, HV302G, GL412N and GL422N.
Is the RC402N the same as the RC402?
No. The older RC402 (no N) only fits lasers with no N and no S in the model name. If your laser ends in N or S, you need the RC402N.
How far does it reach?
Up to 330 ft (100 m), per Spectra’s GL412N and HV302 datasheets. The ST805 Signal Transporter typically doubles that.
What batteries does it take?
Two AA batteries. Spectra ships it with alkalines; rechargeable AAs can be used but must be charged outside the remote.
