To clear an "ER 1" error you have to give the radio it's own version of the three-finger salute (Ctrl-Alt-Del): press [F] and the "D" button on the keyboard while turnning the radio on. This resets the CPU (which totally wipes the memory channels).

"ER 1" situations are frequently caused by a dead coin cell internal to the radio. The Radio Shack page at this web site has an article on curing this problem: "Replacing the Memory Backup Coin Cell in the HTX-202 and HTX-404 Handheld Radios" by by Richard Luts KD4SEV and Craig LaBarge WB3GCK.
