Up Arrow Button: Pressing this button once will increase volume by 1 step until it
reaches maximum volume after which there is no effect. Give the button a solid press for each
step.
Down Arrow Button: Pressing this button once will decrease volume by 1 step until it
reaches zero volume after which there is no effect. Give the button a solid press for each step.
For either button, pressing and holding the button will cause continual step commands to be sent
to the attenuator, making a smooth transition from loud to soft or the reverse.
There is a slight
delay in beginning the continuous commands so you can do individual presses for smaller
volume changes, if you want.
Lock Button: This is the mute function. It is a toggle and will alternately mute and un-
mute the volume control. Unlike the up and down buttons, you must let go of the mute button
and press it again to make it toggle. Also, if you press the Up or Down buttons when in the mute
condition, it will automatically unmute the sound and start ramping the volume up or down from
its pre-mute level.
Unlock Button: This unique function will lower the volume level a significant amount all
at once (or go to zero if you are already at a very low volume level). So, if you want to turn
down the applause at the end of a cut, for example, but want to still hear when the next cut comes
on, just hit this button. It toggles back to the original volume level after you release the button
and press it again, same as the mute. Here, too, if you press either the Up or Down buttons in the
reduced volume condition, the system will start ramping up or down from that level.
Another thing to note is that the control system will remember where it was when you turn off
the power to your preamp and turn it back on again (except for mute or turn-down settings. The
mute and turn-down are always off at power-up). This will enable you to keep your master
volume on the preamp set at a fixed level and not have the sound come on too loud or soft.
Battery life is a function of how much the remote gets used and ours has lasted over 6 months so
far. But just in case, an extra controller, two extra 27A batteries, and a suitable screwdriver have
been included with the Z302 set so you are never without your control! Replacing the battery is
simple – place the remote face down on a flat surface, remove the 3 small screws and gently
separate the black back and front case pieces. Take off the black back. Try not to disturb the
position of the rest of the unit while you pry out the old battery and put in the new one. Replace
