Care and Maintenance
Factory Reset
At some point, it may be necessary or desirable to reset your MasterKeyer to “factory
default” settings. Certain combinations of settings, for example a user interface speed set
faster than you can copy or send, may make it difficult to recover to settings you can use.
There are a number of reset options available. From the paddle command menu, sending
“
XA
” will reset all user settings to their initial defaults. This will not erase the contents
of the message memories, so you can do it without needing to re-program your messages.
The “
XM
” command will leave the user settings alone, but will erase the contents of all
thirty message memory slots. In each case, the keyer will prompt you for confirmation
before completing the reset or memory wipe. You must respond with “Y” to complete
the action, otherwise it will be canceled. These commands can also be sent from the PC
as
/XA
or
/XM
.
If you cannot use the command menu due to an incorrect setting, there is another option.
Power your MasterKeyer off. Hold down memory buttons 2 and 5 while powering on.
The keyer will turn buttons 2 and 5 orange and send “
RESET?
” to confirm your choice.
You must release the buttons, then press buttons 2 and 5 again to complete the reset.
Hold the buttons in until they turn red, then release. This is similar to the command
menu “
XA
” reset – it will do a complete reset of all user settings, but will not delete the
contents of the message memory slots.
Cleaning
Your MK-1 is equipped with a sturdy aluminum cabinet and a tough, textured powder
coat finish. Given normal care it should provide many years of reliable service. No
periodic or preventative maintenance is required under normal conditions.
You can clean your keyer cabinet with a damp cloth and mild cleaner. To avoid anything
getting in through the openings, do not spray liquid cleaners directly onto the keyer. Do
not use abrasives, harsh cleaners or solvents such as paint thinner or acetone. For
stubborn residue or stains, a little isopropyl alcohol can be used on the metal surfaces.
Commercial adhesive removers such as “Goo-Gone” can be used for label residue. Do
not use any solvents (including adhesive removers) near plastic parts, especially the
function buttons. Of course, always make sure your keyer is turned off and disconnected
from any power source and from your computer before cleaning.
Firmware Updates
The operation of your keyer is controlled by its internal program. The program is stored
in non-volatile FLASH memory, meaning it is retained while power is off but can be
altered when needed. From time to time, it may be desirable to update the internal
program (the firmware) that controls your MasterKeyer MK-1. Firmware updates can
