CATTRON

MK controllers are equipped with an internal antenna and the typical operating

(transmitter) range is in excess of 500 feet (160+ meters). It should be understood that operating range
varies with environmental conditions. Should the transmitter go out of operating range, all motions
will cease.

As previously mentioned, operational security is maximized by the need to use a stainless steel
electronic i-Key for controller operation. However, there is an additional and very significant
operational advantage of the CATTRON

i-Key concept. It is that individual system address,

operating frequency and keypad configuration may be permanently stored in the i-Key, depending on
the type of MK controller supplied. Therefore, CATTRON

MK series controllers belonging to the

same family at a user location can be identical - only the i-Keys are different. To simplify, each i-Key
is color coded and labeled for an individual control system family, thus, any CATTRON

controller will run any CATTRON

receiver/decoder belonging to the same family as long as the

correct i-Key is used. As the result, this unique operating concept reduces the need for specific spare
remote controllers. Our unique family of MK Series controllers is identified on the next page.

All CATTRON

MK series controllers are powered by disposable 3-Volt alkaline or re-chargeable Ni-

Cad battery packs. In normal operation, a green LED ‘flashes’ with each function command message
and a ‘beep’ is sounded when a key is pressed. When the battery voltage becomes low, a separate
yellow LED flashes, alerting the operator that the battery pack needs to be replaced or re-charged soon.
Battery packs are easily and quickly replaced without the need for tools by turning two knurled
thumbscrews and removing the battery cover-plate located within the confines of the armorized rubber
bottom end-cap. The battery pack makes positive contact without snaps or plugs and has no wires to
break; simply drop it in, and replace the battery cover-plate.

Ni-Cad battery packs can be re-charged ‘in-situ’ and do not need to be removed from the controller
housing. To enable such battery charging to be carried out, an optional ‘standard rate’ (10-hour)
battery charger is available for all CATTRON

MK series controllers. One end of this charger is

connected to a standard 120VAC outlet, the other plugs into a covered socket located on the curved
underside of the controller. A ‘rapid rate’ (1-hour) battery charger is available on request.

A belt loop strap is available for all CATTRON

MK series controllers. This is quickly and simply

installed to a ‘D’-ring located on the curved underside of the controller. Also, an optional shoulder
carrying strap is available on request.
