Even at the fastest rate, you have to look closely to see the motors turning.
On some of the handsets, there is a "Fast" speed. Press the button for the direction you want to go, then press the OPPOSITE direction button, and the signal to the motors moves at maximum speed.. This is not the case for ALL Celestron handsets, but some work this way.
But basicallly, you are correct. This mount will not slew quickly. The motors are for fine movement. If you want to move across the sky, you will need to unlock the axis lever and manually slew.

Hopefully yours is working, I had a HC go kaput on me, the lights would still work properly but the main chip inside had fried.

The news may not be all bad. The maximum rate is only 8 times sidereal; that's around 2 degrees per hour. Oops - got that upside down, didn't I! Correction - 8X would be about 2 degrees per MINUTE. The motions will be very slow when functioning normally; you may not notice them at all.

I just gutted one failed unit and used the box and switches to make a controller for a CI-700 mount. So if you want to get rid of this non-RoHS device I'll give you $10 for it.
Hands-on-Optics used to sell just the replacement handbox. Drop a line to Gary Hand.

Gently rest a finger on the RA motor with the thing switched on. If it's working, you can feel a "ticking", at about 2Hz IIRC. Press the RA control buttons on the HC to see if there is a change to the tick rate. On the Dec motor, the same applies except that there won't be anything detectable with no buttons pressed.
The whole thing does move imperceptibly slowly and is almost completely silent under all circumstances, so you can't tell if it's working without either looking through a scope or feeling for the motor ticks.
Hope it's all ok...
