Impulse Micro Trac 6800

[tom l. thomas]

We recently purchased a boat with an Impulse Micro Trac 6800 depth finder. It will turn on, but I cannot set the depth alarm, deep alarm or range. I do not have an owner's manual for it. I realize the company producing this unit has been out of business for quite some time.

Could anyone having this unit with an owner's operating manual please contact me? I would really appreciate it.
