| Arming | Enabled | Ch1 to center position (off) | 
| Low Voltage Cutoff | Enabled | Led 5-flash if triggered (LVC) | 
| Cruise control | Enabled | Outputs 'hold' last position on signal loss/Tx switched off | 
| Inactivity Sleep | Enabled | Invoked after 1hour, Switch Rx off and on to restart | 
| Battery Voltage flashes | Enabled | Press Bind button (Ch5) briefly and count flashes as described here Flashes appear on LED2 output (P1) | 
2. CONNECTIONS:

Pads are in different positions but the connections are very similar to the previous version Rx65-1
The minimum connections are Battery to +/- and Motor to H1a/H1b.
3. BINDING
Bind once:
1. Switch Rx on and wait ~20s until led flickers fast.
2. Switch Tx on in bind mode.
3. Rx led should flash slowly; wait for it to go solid.
Change distance between Tx/Rx if binding does not work.
4. LED:
Led On  = perfect reception (real-time indicator).
1 flash = Scanning (~2sec between flashes; no signal or not bound if never stops).
5 flash = LVC/Brownout (voltage went too low; check battery/motor load).
5. PAPERCLIP CHANGES:
The following changes can be made by simply shorting two pads together (eg: with a paperclip):
1. Perform a 'Hard reset' (factory reset).
2. Change motor control between 'low off' and 'center off'.
3. Enable/disable LVC (eg: when using Nicads, NiHMs, LiFe cells).
4. Enable/disable Selecta.
5. Enable/disable Cruise Control/Failsafe.
6. Enable/disable the Menu feature.
'Paperclip' changes
6. PROGRAMMING:
This receiver has many other options that are described on the features page.
These are changed using a technique called 'programming': v611.
