  We present results of the monitoring of the black hole candidate 1E
1740.7-2942 with INTEGRAL, in combination with simultaneous observations by
RXTE. We concentrate on broad-band spectra from INTEGRAL/IBIS and RXTE/PCA
instruments. During our observations, the source spent most of its time in the
canonical low/hard state with the measured flux variation within a factor of
two. In 2003 September the flux started to decline and in 2004 February it was
below the sensitivity level of the INTEGRAL and RXTE instruments. Notably,
during the decline phase the spectrum changed, becoming soft and typical of
black hole binaries in the intermediate/soft state.
