Maybe you may have to call the dreaded we-keep-you-on-hold-forever-hoping-you-will-hang-up-before-we-answer #....aka 824-TSTT
Alternatively, you could use that little button on the underneath called Reset...but you'll lose any settings that you have changed from the defaults. Or worse yet, you may now be
forced to call TSTT cos the actual default user/password isn't admin/admin
muhahahhahahha...all your hopes are belong to TSTT
