Universal Remote Control URC-300 ユーザーズマニュアル

Each of your Customizer Devices actually contains five
pages. However, only four pages are visible in the 
factory default setting. One page is hidden in each
device. If you wish to use the hidden page, you can
ADD it. If you don’t want to use some of the existing
pages, you can HIDE them. You can add or hide pages
on devices OR on your favorite channel pages using
this simple process: 

Note: Be sure to program your Macros before you hide
pages with potential macro in them. You can’t access
hidden pages during macro setup. However, after you
finish Macro setup, you can hide pages without affecting
operation of your macros.

Enter SETUP mode by pressing and holding both
MAIN and ENT for three seconds. 

Note: You have 30 seconds for each step, otherwise the
Customizer will time out automatically. 

Press the EDIT button.

Press the PAGE button.
