Statutory Requirements
EC: Unlicensed operation limits the radio power. High gain aerials may
only be used to compensate for cable losses.
Internal Battery Connection:
If unit has internal battery option, the battery is not connected to
1 wavelength
unit during shipping.
minimum
To connect the internal battery:
· Remove the battery holder by removing the two Philips
screws and then remove the battery bracket.
COLINEAR
· Locate the battery connector on the ERT-A2 circuit

board at the top right of battery as shown in picture
below.
· Plug the battery cable connector into the two pin
connector on circuit board being careful to get the
correct orientation for the connector key.
