Note 6: Reserved for module tuning and compulsive for system application that any circuit doesn’t be connected to

them.

Note 7: The mounting studs are provided for transceiver mechanical attachment to circuit board. They may also

provide an optional connection of the transceiver to the equipment chassis ground. The holes in the circuit

board must be tied to chassis ground. It is not recommended that the mounting studs be connected to

signal ground.
