"I don't own an HTX-202, but I own it's sister, the HTX-404. I'll give it to you right out of the manual:

Er1: Internal RAM Error

Er1 indicates that the HTX-404 has detected an error in its battery-backed up memory. This is most commonly caused by a low lithium backup battery, but can also be caused by static discharge or a physical shock. To clear the error, reset the HTX-404 by turning it off, then holding down F + D while you turn it on again. This clears and reinitializes memory.

If the transceiver frequently displays the error, have the battery replaced by an authorized Radio Shack repair center."
