From c479b9975d90de77c8471c91d0d3db8513100add Mon Sep 17 00:00:00 2001 From: Thom Johansen Date: Wed, 13 Feb 2008 13:32:44 +0000 Subject: FS #8340 by David Bishop. Remove contractions from the manual, as this seems to be common practice in this format and makes it easier to read for non-native english speakers. New manual work should try to adhere to this. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@16302 a1c6a512-1295-4272-9138-f99709370657 --- manual/plugins/alpinecdc.tex | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) (limited to 'manual/plugins/alpinecdc.tex') diff --git a/manual/plugins/alpinecdc.tex b/manual/plugins/alpinecdc.tex index 008bb62975..8d0fcee746 100644 --- a/manual/plugins/alpinecdc.tex +++ b/manual/plugins/alpinecdc.tex @@ -13,11 +13,11 @@ Hookup to Archos works by connecting the headphone output including the remote pin (you need a 4-ring 3.5 mm plug for that) to the changer jack of the radio.
