ACHTUNG !
This information if for an SM2535X NOT a 35X-7 !
The last number means there is some minor change to the set.
Remote called for is a 124-17-01
The 19" chassis ONLY calls for a 124-17
IIRC the only difference is cosmetic.
This is what it looks like.

ALL battery operated ultra Zenith remotes use the same freqs.
Odds are the hand unit is bad. Never seen a set with that problem
or a remote that needed adjustment.
BTW the set is from the mid line. Mostly the same as top of
line but does not have auto on/off & space phone. Also the top
sets had IR remotes.
