“Many of he (consumer) complain s received by he Commission arise
from a emp s o receive elevision s a ions far beyond heir normal range.
Due o he na ure of he frequencies used, elevision recep ion is possible
only if he receiver is loca ed wi hin a rela ively shor radius of he rans
mi ing s a ion. A he presen ime, he maximum range of elevision recep
ion varies from 20 miles o 40 miles, depending on he ype of s a ion
involved and he amoun of power i is presen ly using. In general, a ele
vision s a ion loca ed in a large ci y (a “me ropoli an s a ion”) using full
power can be received up o 40 miles from i s ransmi er. However, if he
me ropoli an s a ion is using less han full power, i s range may no be more
han 20 miles from i s ransmi er. Many “me ropoli an s a ions” a he
presen ime are using emporary low-power facili ies pending receip of
new equipmen which will permi hem o use he full power assigned o
hem. Likewise, a elevision s a ion loca ed in a smaller ci y (a “communi y
s a ion”) which is assigned rela ively low power, canno be received more
han 20 miles from i s ransmi er. Though long-dis ance elevision recep
ion is repor ed on occasion, his is a “freak” condi ion and canno be de
pended upon for regular service."

PRELIMINARY CONSIDERATIONS
The Candid T-V is an exper ly engineered elevision receiver, capable
of reproducing high defini ion pic ures of fine de ail and brilliance wi h
accompanying sound. Every effor has been made by Pilo Radio o crea e
a small, compac , ligh weigh uni , wi h “large se ” performance s andards,
which can be carried readily from room- o-room, from house- o-house, or
from elevision ci y o elevision ci y. Design, uning and adjus men of con
rols have been radically improved and simplified so ha you will find
enjoymen and enligh enmen in he easy opera ion of he Candid T-V. Wi h
i s smar lea here e carrying case and an enna, he Candid T-V represen s
an ou s anding con ribu ion o he elevision indus ry as he firs “quasi
por able” elevision receiver and he perfec modem raveling companion
for he elevision en husias
POWER SOURCE

OPERATION
FRONT PANEL CONTROLS
Scanning across he fron panel from lef o righ , he con rols and heir
func ions are as follows:
Figure 1.—Fron panel con rols
Off-On Volume—'This con rol serves he dual purpose of power swi ch
and sound volume con rol, similar in opera ion o such con rols on s andard
radio receivers. In he ex reme coun er-clockwise posi ion he power swi ch
and he receiver is a OFF. To urn on he receiver, ro a e his con rol clock
wise un il a click is heard. Con inuing o urn he con rol clockwise increases
he level of he sound accompanying he elevision pic ure.
age Four
Brigh ness—This con rol, as i s name implies, adjus s he brigh ness
(background ligh ing) of he elevision pic ure. I is ac ually he coun erpar
of he one con rol in a s andard radio receiver. As you well know, he adjus 
men of he one con rol in a s andard radio receiver ei her accen ua es or
a enua es he high or low ones o sui he as e of he lis ener, and here is
only one correc se ing which produces so-called “high-fideli y.” In ele
vision, he BRIGHTNESS con rol performs he same func ion for he whi e
and black por ions of he elevision pic ure. Advancing his con rol clock
wise will accen ua e he whi e por ions of he pic ure, and inversely urning
i s coun er-clockwise will darken he black por ions of he pic ure. Ini ially
he correc se ing of he BRIGHTNESS con rol is he one ha produces
a very fain glow on he elevision screen, when no s a ion is uned in. The
signal ransmi ed from he elevision s a ion will hen au oma ically se
he normal and lifelike background level of he elevision scene. The con rol
can be changed fur her, if so desired, o sui your own individual require
men s. However, oo high a se ing of he BRIGHTNESS con rol will resul
in a “washed ou " pic ure and he appearance of whi e racer lines across he
screen (Refer o Fig. 4). The se ing of he BRIGHTNESS con rol should
no be affec ed by a change in room illumina ion.
Tuning-High Low—This se of con rols consis s of a double knob wi h
correla ed func ions. The lhrger rear knob (TUNING) is he elevision
s a ion selec or, similar in opera ion o he con inuous uning knob on a
s andard radio receiver. This uning con rol can be ro a ed con inuously
ei her clockwise or coun er-clockwise, and is synchronized wi h he channel
dial scale loca ed below he pic ure ube. The smaller fron knob (HIGH
LOW) is a band swi ch wi h wo posi ions: LOW (clockwise) covering
channels 2 hrough 6, designa ed by he whi e por ion of he dial scale; and
HIGH (coun er-clockwise) covering Channels 7 hrough 13, designa ed by
he black por ion of he dial scale.
Con ras —This con rol adjus s he shading of he elevision pic ure and
permi s you o choose a pleasing range of shades from in ense black o clear
whi e. In addi ion, he CONTRAST con rol is ac ually he exac coun erpar
in elevision of he volume con rol in a s andard radio receiver, since i
regula es he s reng h of he elevision signal received which resul s in
differen shadings of he pic ure. By ro a ing his knob clockwise, he
s reng h of he elevision pic ure is in ensified, and he dark por ions of he
pic ure will appear blacker and he brigh ones whi er. Since he CON
TRAST con rol affec s in par he shading of he elevision pic ure, i should
be adjus ed o correspond wi h he se ing of he BRIGHTNESS con rol.
Too high a se ing of he CONTRAST con rol, in par icular, should be
avoided in order o preven dis or ion, ins abili y and a loss in grada ion
of shading from deep black o full whi e. A li le prac ice in a aining a good
balance be ween se ings of he BRIGH NESS and CON RAS con rols
will enable you o ob ain quickly he ype of pic ure presen a ion mos pleas
